    Before

    I

    went to

    Cambridge

    in

    the au-

    tumn

    of

    1960,

    I

    did

    not

    know

    the work

    of

    the

    Italian

    architect,

    Giuseppe

    Terragni.

    During

    that

    year

    Colin

    St.

    J.

    (Sandy)

    Wilson

    gave

    me

    a

    copy

    of

    Alberto

    Sartoris'

    'Encyclopedie

    De

    L'Architecture

    Nouvelle'

    which

    had

    a

    section

    devoted

    to Ter-

    rangni's

    work.

    The

    following

    summer,

    I travelled

    with

    Colin

    Rowe

    to

    Como,

    where

    I

    saw

    much

    of

    the

    work

    for the

    first

    ime.

    For

    many

    of

    the

    inter-

    vening

    years

    I

    have

    been

    working

    almost

    intui-

    tively,

    probing

    into

    the

    formal

    aspects

    of

    Ter-

    rangni's

    work,

    with

    few

    preconceived

    ideas

    as

    to

    what

    might

    be

    the

    results.

    In

    order

    to

    give

    this

    work

    a

    focus,

    in

    1966

    I

    began

    looking

    into other

    disciplines

    wherenproblems

    of formhad

    beentpre-

    sented

    withinsome

    critical framework.

    This

    took

    me

    into

    linguistics,

    and

    more

    particularly

    to

    the

    work

    of Noam

    Chomsky

    in

    syntax.

    From this

    re-

    search

    itawas

    possible

    to

    make

    several

    analogies

    between

    language

    and

    architecture,

    nd

    more spe-

    cifically

    to construct

    a crude

    hypothesis

    about

    the

    syntactic

    aspects

    of architectural

    form.This then

    helped

    to clarify

    some

    of the

    formal

    problems

    in

    the

    work of Terragni.

    Equally,

    as work in

    both

    these

    areas

    continued

    simultaneously,

    the

    empiri-

    cal

    evidence

    gathered

    from the work

    on

    Terragni

    helped

    to

    refine

    nd restructure

    he

    initial

    hypoth-

    esis. From

    this rather

    unscientific

    method

    two sep-

    arate

    theses

    have

    developed:

    one

    concerning

    a

    theory

    of

    form in

    architecture;

    the

    other

    concern-

    ingthe

    developing

    ofbideas

    about

    transformational

    methods

    which

    can be interpreted

    from

    a formal

    analysis of the work of Terragni. The following

    article

    is

    two

    parts

    taken

    out

    of

    context

    from

    the

    latter

    work.Therefore,

    t s intended

    to

    be as

    much

    an

    introduction

    s

    it

    is

    an exploration,

    in

    that it

    is

    not

    a

    definitive

    presentation

    of

    a

    critical

    method;

    it

    merely

    presents

    some

    fragments,

    without a

    gen-

    eral matrix,

    f

    work

    n

    progress.

    One

    of the dominant

    and

    re-

    curing

    themes of

    Twentieth

    Century

    painting

    and architecture

    has been

    expressed

    in

    a

    concern

    for the

    rile

    of

    the

    "object".

    This

    was

    especially

    true

    in

    the so-called

    "heroic"

    period

    of

    the

    Modern

    Movement.

    El Lissit-

    zky,

    when he

    firstcame

    to Berlin

    in

    1922,

    published

    a little-known

    mag-

    azine

    withthe title

    of

    "Veshcsh,

    Geg-

    enstand, Objet" -translated

    into

    English

    literally

    "Object".

    Kasimir

    Malevich,

    Lissitzky's

    teacher,

    had

    previously

    written

    book

    which

    ap-

    peared

    in

    German

    in

    1927

    under

    the

    title

    of "Die

    Gegenstandlose

    Welt"

    in

    English

    "The

    Objectless

    World'.

    As the

    difference

    in these

    titles

    might

    imply,

    their

    ideas

    were

    essentially

    in

    opposition

    although

    a

    basic

    concern

    was the same.

    This

    concern

    was manifest

    in

    an

    attempt

    to divest

    objects

    of

    their

    traditional,

    or associational

    meanings;

    in

    a

    sense, to change society's knownre-

    lationship

    with its

    object

    world.

    The

    underlying

    rationale

    for

    this

    activity

    was

    somehow

    involved

    with

    expos-

    ing

    society

    to the realization

    of

    the

    ultimate

    banality

    and

    poverty

    of the

    extant

    "object"

    world;

    and at the

    same

    time

    to

    suggest

    that

    t

    was

    pos-

    sible,

    through

    the

    medium

    of

    form,

    and

    more

    precisely

    "new form"

    understood

    as

    "'objects"

    devoid

    of

    a

    traditional

    meaning

    or

    context

    -

    to

    suggest

    not

    only

    new

    meanings,

    but

    further,

    a

    new

    awareness

    of

    the

    physical world.

    This

    same

    concern

    was

    made

    manifest

    in

    physical

    form

    through

    many

    different

    methods;

    Fernand

    Leger

    and

    others

    worked

    with

    forms

    of collage,

    taking

    commonplace

    ob-

    jects

    and

    through

    a change

    in

    con-

    text

    sought

    to give them

    a

    symbolic

    and formal

    significance

    beyond

    their

    traditional

    reference.

    The

    distinction

    between a Leger and

    a Malevich,

    while

    perhaps obvious on a

    strictly

    formal

    level, is

    important

    n the con-

    text

    of the following

    discussion.

    Legertook traditional"objects" with

    known

    meaning, and

    by

    changing

    their context

    sought

    to

    invest them

    with

    new meaning.

    Malevich

    sought

    to do

    this, by

    creating a new

    object

    world of pure

    formalrelationships-

    through

    geometric

    abstraction.

    Architecture,

    unlike

    painting,

    is constrained

    by

    the

    presence

    of

    actual

    ""objects"

    -

    with

    the real

    dimensions

    of form

    and

    space.

    Whereas in

    painting the relationship

    of

    the

    forms can

    be

    used

    to

    create

    the illusion

    of

    space,

    in

    architecture

    the

    relationship

    of the

    forms

    is

    the

    space.

    Therefore,

    unless

    one talks

    of

    the

    reality

    of the

    painted

    surface,

    the

    canvas

    itself,

    painting

    is

    inherently

    involved

    in abstraction

    -

    i.e.,

    the

    use

    of

    illusion

    in

    the

    creation

    of

    space.

    No

    such

    procedure

    is

    neces-

    sary

    in

    the creation

    of

    architectural

    space.

    The

    mere

    presence

    of

    some

    formof

    construction,

    whether it be

    two

    walls

    or

    a

    grid

    of columns

    and

    beams,

    will

    necessarily

    define,

    sug-

    gest,

    and

    imply

    space.

    Furthermore,

    in

    painting,

    the

    plane

    of the

    canvas

    provides

    a

    given

    frame

    of reference

    for he

    understanding

    of

    any

    abstract

    or

    conceptual

    structure

    within

    the

    painting.

    In architecture

    there

    is

    no

    given

    frame for

    understanding

    or

    delineating

    the

    abstract

    structure,

    s

    the

    viewpoint

    is

    constantly

    chang-

    ing.

    Painting

    is understood

    through

    perception; architecturethroughap-

    perception,

    or the

    sum

    of

    many

    perceptions.

    Therefore,

    if

    one

    were to set

    the

    same

    problem

    for n architecture

    -

    that of

    finding

    new

    meaning

    from

    formal

    constructs

    -

    a

    necessary

    first

    tep,

    because

    of the

    presence

    in

    architecture

    of actual

    physical

    rela-

    tionships,

    would

    be

    to

    provide

    a

    means

    whereby

    abstract

    relation-

    ships

    were

    conceivable

    as

    independ-

    ent

    of these

    actual

    relationships

    Here

    another

    comparison

    between

    paintingand architecturemighthelp

    clarify

    this

    difference.

    In the

    paint-

    ing

    of Fernand

    Leger

    and

    also

    to a

    lesser

    degree

    in

    Juan

    Gris,

    the ab-

    straction

    in a sense

    could

    be con-

    sidered

    an actual

    one -that

    is de-

    pendent

    on the

    distortion

    of

    known

    objects;

    it

    was

    an

    abstraction

    of

    the

    percept.

    On the other

    hand, people

    like

    Piet Mondrian

    and

    Kasimir

    Mal-

    evich were

    dealing

    not so much

    with

    abstractions

    of objects

    as they

    were

    with structures of pure form, and

    thus with relationships derived from,

    what might be called, formaluniver-

    sals,

    or with

    abstractions

    of

    a

    con-

    ceptual

    nature.'

    In architecture

    both

    types

    of

    relationships

    exist simultaneously.

    There

    is a surface

    aspect essentially

    concerned

    withthe

    sensual

    qualities

    of the object;

    that is

    aspects of

    its

    surface,

    texture,

    color,

    shape, which

    engender

    responses

    that

    are

    essen-

    tially perceptual.

    There

    is also

    a

    deep

    aspect

    concerned

    with

    concep-

    tual

    relationships

    which are

    not

    sen-

    sually perceived;

    such

    as

    frontality,

    obliqueness,

    recession,

    elongation,

    compression,

    and

    shear,

    which are

    understood

    in

    the

    mind.

    These are

    attributes

    which accrue

    to relation-

    ships

    between

    objects,

    rather han

    to

    the

    physical

    presence

    of the

    objects

    themselves.

    For

    example,

    flatness is

    a characteristic

    of an

    object

    while

    frontalitys an attributewhich an ob-

    ject

    may

    assume

    in

    relation

    to

    an-

    other

    object

    or

    in

    relation to

    a

    pre-

    ferred

    viewpoint

    of

    an

    object.

    Frontality

    is

    not

    an

    empirical

    rela-

    tionship,

    but

    rather

    is

    implied

    from

    the

    particular

    placement

    of form

    n

    a

    specific

    context.

    The

    usefulness

    of

    the

    spatial

    abstractions

    of the

    deep

    aspect

    is

    in

    their

    capacity

    to

    provide

    a

    structure

    for

    implied

    meaning

    as

    opposed

    to

    explicit

    meaning.

    In

    ad-

    dition there

    must

    be a

    framework

    which

    would

    provide

    for some form

    of relationship between both these

    aspects.

    This then

    raises

    the

    ques-

    tion as

    to the nature of such a struc-

    ture

    and how

    it

    can be

    developed

    to

    clarify

    the

    interpretation

    of

    spatial

    abstractions.

    Here another

    analogy

    is use-

    ful;

    this time between

    architecture

    and

    language.

    In

    the context

    of

    the

    present

    discussion,

    language

    will be

    considered

    as one

    type

    of

    environ-

    ment

    which

    can

    be said

    to

    have

    a

    structure;

    that

    is,

    it has a series of

    elements which have

    both definable

    properties and definable relation-

    ships

    between

    elements. These

    structures

    usually

    can

    be defined

    or

    described

    in

    terms of their

    iffer-o

    ences or similarities to other like

    structures. The structure f a linguis-

    tic

    environment,or

    more

    explicitly

    a

    language,

    can be said

    to exhibit

    sim-

    ilar

    characteristics to

    a physical en-

    vironment

    -

    and in

    this case to an

    architecture. Both language

    and ar-

    chitecture can be seen in terms of the

    three semiotic

    categories: pragmat-

    ics, semantics,

    and

    syntactics.

    Tra-

    ditionally, architecturehas been un-

    derstood in

    these

    terms, even

    though

    its

    discourse has

    not been

    explicitly

    formulated n this manner. It s worth

    noting

    that most

    discussions of mod-

    ern

    architecture

    have

    been

    mainly

    concerned either with pragmatic is-

    sues

    -

    the relation of

    formto func-

    tion or technology; or

    with semantic

    issues -the

    relation of

    form to

    meaning

    and

    iconography.

    However,

    if

    architecture s to

    provide a seman-

    tic

    interpretation

    ither

    in

    terms

    of

    function

    and

    program

    -

    the

    elabo-

    rationof facts

    -

    or

    in

    iconographic

    terms the

    elaboration

    of

    values

    then

    by

    the above

    given

    terms

    it

    must

    have

    a

    syntactic

    component

    through

    which

    this

    meaning

    is

    mediated.

    The notion

    of

    syntax

    is not

    a

    new

    one for an architecture. Until

    this centurythe construction of ar-

    chitectural

    grammars

    was

    a

    common

    occupation. Many

    of

    these

    gram-

    mars,

    whether or

    not

    they

    were

    mod-

    eled

    on the then

    existing

    form

    of

    language grammars,

    failed to realize

    certain differences between archi-

    tecture

    and

    a

    written

    anguage.

    One

    important

    difference

    in

    this

    context,

    is that

    in

    architecture

    the

    object

    it-

    self has no

    agreed

    upon

    or intrinsic

    meaning

    other

    than

    as its

    shape

    might

    be

    a

    natural

    sign,

    as

    in

    the

    case

    of an

    arrow,

    or as

    might

    ccrue

    to a culturallyreceived symbol, as in

    an

    Ionic

    colonnade.

    In

    language,

    the

    object-word

    is a

    sign having

    a

    com-

    mon,

    agreed upon

    meaning.

    The

    in-

    formation does not come

    directly

    from its

    formal

    structure,

    but from

    an

    agreed upon

    convention

    given

    to

    a

    particular

    structureof

    form.

    n

    lan-

    guage

    the

    formation

    of

    a

    word,

    its

    order

    and

    form

    re not

    arranged

    nec-

    essarily

    to

    engender

    an

    aesthetic

    re-

    sponse;

    the

    primary

    concern

    is

    not

    with the

    placement,

    shape,

    and size

    of

    letters or

    whether

    they

    can

    be re-

    arranged in different ombinations.

    In

    architecture,

    in

    a

    sense

    because

    there

    is no

    a

    priori

    convention

    or

    agreed meaning in respect of form0

    straight

    wall

    next

    to

    a curved wall

    has not only a deep

    level formal re-

    lationship

    but also produces an aes-

    thetic

    response to the contrast or

    tension between the

    two forms. Thus

    unlike

    language

    there

    is a

    primary

    response

    to

    both the

    percept

    or sur-

    face

    aspect and to an

    abstract or

    deep

    aspect.

    This is

    a

    complicating

    fact when considering

    syntax in ar-

    chitecture. In any space the real

    physical qualities

    of objects

    and

    the

    perceptual

    response

    to them

    will

    al-

    ways

    tend

    to obscure the

    conceptual

    response

    and make the

    use

    of ab-

    straction as a

    syntactic

    means more

    difficult

    than

    in

    either

    painting or

    language.

    Therefore,

    if a syntax

    in

    architecture

    were to

    be

    developed, it

    would

    presume to

    mediate

    between

    the

    intended

    meaning which could

    be

    derived froma

    conceptual struc-

    ture,

    and the

    possible

    distortions

    of

    this

    meaning

    whrch

    might

    occur

    through

    the

    lack

    of

    an

    understand-

    able

    relationship

    between

    physical

    fact,

    and this

    conceptual

    structure.

    And

    because the

    physical

    fact does

    not

    represent

    an

    agreed

    upon

    sign

    structure,

    t

    may

    be

    argued

    that the

    syntactic

    dimension

    is

    therefore

    more crucial to an

    architecture

    than

    to a written anguage. Equally, since

    there

    is no

    sign

    system,

    there would

    seem to be no one

    specific syntax

    which

    could structure the

    physical

    fact.

    Therefore,

    the

    syntax

    compo-

    nent

    for an

    architecture

    might

    have

    to

    provide

    for

    ny

    number of

    specific

    syntaxes.

    The

    proposition

    that

    a

    sur-

    face and

    deep

    aspect

    exist as

    a

    si-

    multaneous condition

    in

    any

    archi-

    tecture,

    and the

    corresponding

    need

    to

    provide

    a

    syntax capable

    of dis-

    tinguishing

    between the

    physical

    re-

    lationships

    of

    real

    space

    and

    the

    im-

    plied relationships of conceptual

    space

    -

    between what is

    empirical

    and what is abstract

    -

    becomes

    central

    to the

    following

    discussion.

    It is

    here that the

    analogy

    to

    lan-

    guage

    and

    more

    specifically

    to

    the

    work of Noam

    Chomsky

    s

    important.

    There are

    two ideas

    in

    Chom-

    sky's

    work

    which

    seem central to

    this

    argument.

    First,

    that

    it

    is

    possi-

    ble

    and

    even

    necessary

    to

    separate

    syntax

    from

    emantics;"

    and

    second,

    that

    within

    the former t is

    possible

    to

    discern

    two

    aspects

    -

    a

    surface

    syntax and a deep level syntax.'

    Chomsky

    defines

    surface structure

    as that

    aspect

    of

    a

    syntactic

    descrip-

    tion which determines the phonetic

    form

    -the physical signal. The

    deep

    structure of a

    syntactic

    des-

    cription

    he says determines

    its se-

    mantic

    interpretation.'

    Deep struc-

    turesare

    generated

    by a

    base

    system

    of

    rules which are

    concerned with

    underlying

    relations, with

    an ab-

    stract order. A

    deep

    structure s im-

    plicit only; it

    is not expressed

    but is

    only

    represented

    in the

    mind.'7

    A

    deep structure may not necessarily

    display

    any similarity

    to the surface

    structure. Deep

    structures are

    con-

    cerned

    with

    providing

    an

    abstract or

    conceptual

    framework

    orthe

    formal

    regularities

    common to

    all lan-

    guages.

    In

    architecture

    t can be said

    that it

    is a

    deep structure

    which

    might

    provide the referent

    tructure

    so

    that meaning

    might

    be derived

    from

    a

    particular

    relationship

    of

    specific

    forms.

    This

    paper

    will

    concern itself

    first

    with

    exploring

    the nature

    of

    the

    relationship

    between the surface

    and

    deep aspects

    of architecture.

    If

    these

    deep

    aspects

    are

    to

    be

    made

    accessible,

    then

    second,

    there is a

    need

    to

    develop

    what

    will

    be called

    transformational

    methods

    for deriv-

    ing and relating specific forms to

    formal

    universals.

    These

    transfor-

    mational

    devices translate formal

    regularities

    into

    specific

    forms. One

    aspect

    of

    the

    specific

    transforma-

    tional

    method,

    used

    below,

    is con-

    cerned

    with

    shifting

    the

    primary

    re-

    sponse

    to

    form from a

    perceptual

    to

    a

    conceptual

    nature

    -

    from

    object

    to

    relationship.

    What

    will be

    argued

    here

    is that

    while

    both

    deep

    and sur-

    face

    aspects

    have

    been

    implicitly

    acknowledged

    as

    part

    of an architec-

    tural

    environment,

    the manner

    in

    which these-aspects can be used to

    inform n

    environment

    has not been

    explicitly

    formulated as

    part

    of

    an

    architectural

    discourse,

    partly

    be-

    cause their

    relationship

    as

    mediated

    through

    transformational tructure

    has

    not

    been

    developed.

    This

    paper

    is therefore ntended as an initialex-

    ploration

    into both the

    dual

    level

    syntactic

    dimension,

    and the trans-

    formational structure

    which

    might

    relate the two levels.

    It is

    possible

    to

    distinguish

    this

    duality

    in an

    architectural

    con-

    text, by looking at two architects

    of the "Heroic

    Period'- Le

    Cor-

    busier

    and

    Giuseppe Terragni

    whose

    work because it exhibits a

    concern for

    syntax

    permits

    a critical

    distinction

    to be made.

    Le

    Corbusier

    essentially

    took

    the forms of known objects

    -

    from

    machines,

    ships,

    and

    aircraft

    Fig.

    1

    & 2)

    -

    and

    derived an

    imagery

    n

    a

    manner that to a degree paralleled

    the work of Leger. The intention of

    this imagery was to force a shift in

    meaning through ts appearance in a

    new

    context.

    This intention can be

    seen as primarily semantic one.

    In Terragni there are obvious

    semantic implications as in his refer-

    ence to historical buildings. For

    ex-

    ample,

    there

    s a similarity

    which

    can

    be seen

    in a

    comparison of the

    plans

    of the Casa del Fascio and the Palazzo

    Farnese and the Palazzo Thiene. But

    while the semantic reference s to the

    high

    culture of the Italian

    Rennais-

    sance,

    the

    ultimate

    intent

    n

    Terrag-

    ni's use of such a plan would seem to

    divest such type forms of theirtradi-

    tional

    meaning,

    and

    instead use the

    formal

    type

    in

    a manner similar

    to

    a

    deep

    level

    syntactic

    structure to

    which

    his

    specific

    forms refer.

    Le

    Corbusier often based his

    work on

    similar

    precedents,

    as

    in

    the

    case of

    the Villa Garches and

    its re-

    lationship

    to the

    Villa

    Malcontenta."

    The

    critical distinction

    between Le

    Corbusier

    and

    Terragni,

    is that the

    particular object for Le Corbusier

    never

    loses its

    semantic dimension.

    Thus the

    syntactic

    ABABA

    structure

    of Garches

    refers

    not

    necessarily

    to

    the

    syntax

    of

    the

    Villa

    Malcontenta

    but rather

    o the

    semantic notion of a

    Renaissance

    "ideal". The

    syntactic

    dimension

    in

    Le

    Corbusier's work

    seems

    to be

    primarily

    concerned

    with

    its surface or

    perceptual aspect

    with

    giving

    full

    semantic value to

    the

    object.

    In

    Terragni

    the

    iconography

    of the

    object

    is

    a

    secondary aspect,

    partiallybecause his work followed

    after Le

    Corbusier

    in

    time;

    and

    thus

    after Le

    Corbusier

    had

    exploited

    the

    symbolic potential

    of these forms.

    Since

    any

    intentional

    conography

    in

    Terragni's

    work is

    necessarily

    re-

    duced,

    it

    is

    possible

    to

    examine

    his

    forms

    in

    their

    syntactic

    dimension,

    and in

    particular

    in

    their relation to

    the

    deep aspect

    of

    syntax.

    One

    purpose

    of

    the

    following

    analysis

    is to

    suggest

    the

    acknowl-

    edgement

    of

    a

    deep

    level

    syntax

    in

    the work of

    Terragni,

    and to make

    more explicit the manner in which

    this

    deep

    level

    conditions the

    spe-

    cific

    forms;

    a

    relationship

    which

    up

    to now has been mainly implicit in

    most discussions of his architecture.

    But in particular the

    analysis will

    study

    the

    specific

    transformational

    method

    used to

    explicate this rela-

    tionship; in this case

    through he an-

    alysis

    of the specific

    form,

    which in

    the

    end

    can be

    understood

    primarily

    in a

    syntactic context.

    it is

    perhaps a

    precarious un-

    dertaking

    to

    initiate the

    develop-

    ment ofsuch a thesis through he an-

    alysis

    of a

    single building. However,

    as was

    stated in the

    preface, this ar-

    ticle makes no

    claims as to its meth-

    odological rigor but

    rather is in-

    tended

    as one of a series

    of inquiries

    into

    the realm of

    syntax. And while

    formal

    analysis is a

    valuable art his-

    torical method,

    in itself

    it can be-

    come

    merely

    descriptive -an

    exer-

    cise in

    intellectual

    gymnastics. In

    the

    following

    discussion, formal an-

    alysis

    will

    be

    used as a

    probing

    de-

    vice to uncover

    traces of

    what

    seems

    to

    be an

    accessible dual

    level

    syn-

    tactic structure in

    the

    work

    of Ter-

    ragni.

    It

    must be

    remembered

    that

    whether

    Terragni

    himself

    con-

    sciously

    worked

    with

    such a

    struc-

    ture is

    not

    at issue

    here.

    One

    transformationalmethod

    which

    is

    evident

    in

    both

    the Casa

    del

    Fascio and the Casa Giuliani-

    Frigerio

    is the use

    of

    pictorial

    am-

    biguity.

    According

    to

    William

    Emp-

    son,

    one

    problem

    which

    might

    call

    for

    the

    use

    of

    ambiguity

    would

    be

    where it is

    necessary

    to

    create

    "a

    unitary

    ituation

    between the

    logical

    conflict of

    the

    denotative and

    the

    connotative."'''

    While

    Empson

    was

    referring

    o a

    linguistic

    environment,

    architecture

    also

    presents

    a

    similar

    conflict.

    It s

    possible

    to

    suggest

    that

    such

    a

    use

    of

    ambiguity

    in

    a

    concep-

    tual

    as

    opposed

    to a

    perceptual

    sense" is one possible transforma-

    tional

    method

    which

    might

    allow

    deep

    level

    structures to

    inform

    pe-

    cific

    physical

    environments."

    Thus,

    the

    use of

    conceptual

    ambiguity

    in

    the

    work

    of

    Giuseppe

    Terragni

    can

    be

    interpreted

    s a

    primary

    ransfor-

    mational

    device;

    the

    attempt

    to

    move from

    an

    object

    or

    percept

    ori-

    entation to a concern for

    making

    ab-

    stract formal

    relationships

    more ac-

    cessible

    being

    one

    aspect

    of this

    method.

    In

    Terragni's

    work,

    concep-

    tual ambiguity s developed from he

    use of two basic

    and

    opposing

    con-

    ceptions

    of

    space.

    The first consid-

    ers

    space

    as

    subtractive,

    or cut

    away

    from a solid.

    In this context

    space

    is considered

    to be metaphor-

    ically hollowed

    from an abstract

    solid

    volume.

    The

    second

    concep-

    tion of

    space, which has

    Renais-

    sance

    antecedents,

    considers

    space

    as

    additive, made up of a series of

    implied

    layers,

    much like a deck

    of

    cards.

    Subtractive space

    implies a

    center

    and

    is

    centripetal

    in

    concep-

    tion; additive space is concerned

    more

    with

    the

    periphery,

    with

    edges

    and

    corners, and is

    centrifugal in

    conception.

    Thus

    at a

    conceptual

    level,

    space

    in

    its most neutral

    state is

    seen

    as either

    solid-positive or

    void-

    negative.

    To

    define real

    space

    through

    ome formof

    marking

    r no-

    tational

    system

    implies both a

    deep

    level

    syntax and a set of

    transforma-

    tional

    rules.

    The

    initial

    marking

    of a

    specific

    form

    can

    be

    considered as

    either

    additive,

    if

    one

    is

    filling

    up

    the

    void,

    or

    subtractive,

    if

    one is

    cutting

    away

    from

    he

    solid.

    In

    each

    case

    the

    distinction

    will

    be

    conceptual,

    in

    that the

    value

    given

    to the

    space

    -

    either

    positive

    or

    negative

    is not ac-

    tual

    but

    implied.

    If,

    for

    example,

    one

    is

    taking

    away

    from a solid

    plane

    producing openings,

    these

    openings

    take on an intentionalcharacteristic

    -a

    positive

    one

    -different from

    openings

    leftover when a

    void

    has

    positive

    solid elements

    added

    to

    it.

    Thus

    in an

    analysis

    of

    space

    every

    marking

    in

    an

    additive

    process

    is

    a

    positive

    gesture,

    and

    becomes

    sig-

    nificant when

    compared

    to

    a

    range

    of other

    markings

    possible

    in

    a

    spe-

    cific

    situation.

    Equally,

    every

    void

    in

    a

    subtractive

    process

    takes

    on this

    same

    intentional

    characteristic

    and

    can

    be

    understood

    through

    similar

    process.

    Each

    mark,

    while

    obviously

    having a surface or perceptual char-

    acter,

    also

    can

    be

    considered

    as

    be-

    ing

    intentional

    o the

    development

    of

    a

    deep syntactic

    structure,

    which

    in

    turn

    may

    provide

    clarification

    of

    the

    building's

    semantic

    intention.

    In

    Terragni's

    work an

    ambig-

    uous

    condition is

    developed

    by

    su-

    perimposing

    an

    additive

    on a

    sub-

    tractive

    process-where

    both

    solids

    and

    voids

    carry

    a

    charge

    -which

    can

    be read

    simultaneously

    as

    oscil-

    lating

    between

    positive

    and

    nega-

    tive.

    Thus

    while the dual

    reading

    resides in the percept, its effect is

    not so

    much an

    aesthetic

    one,

    as

    it s

    to

    provide

    a

    notation

    for

    what can

    be

    described as deep level

    structure.

    t

    is

    through

    such a

    method which

    shifts from a

    concern for

    the quali-

    ties of

    "object" to

    a

    concern for re-

    lationships

    between

    objects

    thatthe

    subsequent potential

    forthese

    rela-

    tionships

    to

    carry

    new

    meaning

    can

    be

    proposed.

    In

    the

    analysis

    of

    the

    different

    stages

    in

    the

    development

    of

    the

    Casa

    Giuliani-Frigerio,

    he

    existence of

    a

    deep

    level

    structure

    ecomes

    apparent;

    and

    fur-

    ther

    he

    relationship

    etween

    physical

    fact

    and

    the

    latent

    conceptual

    structure

    is

    made

    more

    understandable.

    This

    relation-

    ship

    is

    initially

    revealed

    in

    the

    dialectic

    between a

    planar

    or

    additive

    structure

    nd

    a

    volumetric

    or

    subtractive

    structure. n

    an

    early

    scheme

    (A),

    a

    volumetric

    eading

    predominates Fig. 3); although here s a

    lateral

    tripartite

    ivision of

    the

    plan

    (Fig.

    4),

    little

    spatial

    striation

    is

    developed

    either

    parallel

    to

    or

    cutting

    aterally

    cross

    these

    planes.

    In

    subsequent

    schemes

    these

    planes

    act as

    datum

    references

    for

    projections

    and

    recessions;

    the

    particular

    nature of

    these

    inflections

    or

    distortions

    of

    the

    initial

    solid"

    volume

    being

    under-

    stood

    with

    respect

    to

    these

    datum

    planes

    in

    both

    plan

    and

    elevation.

    From

    the

    earliest

    sketches,

    the

    shear

    walls

    mark

    a

    square

    on

    the

    ground

    floor

    plan

    (Fig.

    5);

    the

    three

    ypical

    floors

    marka

    square

    and

    a

    half,

    which

    happens

    also to approximate he building imitsof

    the

    site

    (Fig.

    6);

    the

    penthouse

    apartment

    reiterates he

    original

    quare

    of

    the

    ground

    plane

    (Fig.

    7).

    This

    square

    is

    further

    rtic-

    ulated

    in

    section,

    by

    a

    half

    level

    division

    in

    each

    typical

    floor.

    The

    north

    levation

    of

    Scheme

    A

    (Fig.

    8)

    exhibits

    the

    first

    ndication

    of

    the

    intention

    o

    erode the

    primary

    olumetric

    reading,

    in

    the

    placement

    of

    a

    horizontal

    slot

    at

    the

    lower

    part

    of

    the

    facade.

    This

    can

    be

    interpreted

    ntwo

    ways:

    it

    begins

    to

    destroy

    the

    credibility

    f a

    solid

    read-

    ing,

    by

    placing

    thevoid

    in

    such

    a

    way

    that

    it

    would

    seem

    to

    be

    holding

    up

    the

    "solid";

    and because of this, it begins to give a

    planar

    or

    membrane-like

    quality

    to

    this

    surface,

    therein

    suggesting

    an

    incipient

    planar

    structure

    o

    the

    internal

    olume

    as

    an

    alternative

    reading.

    A

    second set

    ofschemes

    (Scheme

    B)

    is

    distinguished

    by

    the

    reversal of the

    stairway

    ocation

    from

    he west

    to

    the east

    face

    of the

    building

    (Fig.

    9).

    This condi-

    tion

    obtains

    in

    all

    subsequent

    schemes.

    Thus,

    while the north

    nd south

    facades

    remain

    essentially

    the same in

    terms

    of

    the

    formal

    tructure,

    he east

    and west

    fa-

    cades

    are

    reversed.

    The

    rationalefor this

    move,

    as will

    be seen

    later,

    ontributes

    o

    the

    development

    of

    the

    specific syntax.The

    organization

    of the

    plan

    in

    Scheme

    B

    is still

    tripartite

    Fig.

    10).

    How-

    ever,

    the

    stair,

    instead

    of

    being

    located

    within he

    middle

    bay,

    now

    straddles

    the

    bearing

    wall

    between

    the

    end and the

    middle

    bay.

    The

    single balcony

    projection

    re-

    mains on the north

    facade.

    However,

    the

    south facade

    has

    undergone

    transforma-

    tion and

    exhibits

    an

    ambiguity

    n

    the ver-

    tical dimension.

    In

    the

    plan

    of

    Scheme

    B

    the west

    wall

    can be read as a

    screen

    by

    virtue

    of its extension

    to

    the

    south,

    thus

    breaking

    he solid

    volumetric orner

    Fig.

    11).

    Equally,

    the southwest

    corner shows

    anotheraspect of the intentional rosion,

    where the

    balcony

    which

    projects

    beyond

    the

    solid

    corner

    now

    lines

    up

    with he ver-

    tical

    edge

    of

    the west

    facade.

    In the earlier

    scheme this

    balcony merely

    projected

    out

    from he

    internal

    olume

    which

    was seen

    as a

    solid.

    Now

    its

    position

    initiates

    a

    planar

    stratification n the south facade.

    In

    Scheme

    B

    thereis an

    equal

    division

    of

    the north

    acade into

    eight

    parts,

    while the

    opposite

    south facade

    is divided

    into

    only

    seven

    equal

    bays.

    This different ivision

    of

    the

    facades

    reinforces he discontinu-

    ous

    nature fthe

    internal

    ongitudinal

    tri-

    ation

    from

    north

    o

    south.

    In

    Schemes C &

    D

    the

    conceptual

    ambiguityof the northfacade is devel-

    oped

    (Fig.

    12).

    There

    are two

    major

    changes

    in

    the

    formal

    structure of the

    north

    facade

    which

    appear

    in

    these two

    schemes

    which

    clarify

    he

    specific syntax

    being

    evolved

    by Terragni.

    change

    in

    the

    bay

    structure rom he

    eight

    equal

    bays

    of the

    earlier

    schemes,

    to an

    alternating

    AbAb

    bay

    organization (Fig.

    13).

    This further

    mphasizes

    the

    discon-

    tinuity

    n

    the

    longitudinal

    striation

    and

    presents

    a framework

    or a

    volume-plane

    ambiguity

    which is

    subsequently

    devel-

    oped

    on the

    north

    facade.

    A

    second

    and

    perhaps

    more

    significant hange

    occurs

    in

    the transition

    rom

    Scheme

    C to

    Scheme

    D.

    This

    involves

    an

    extension

    ofthe

    inter-

    nal volumethrough he columnlinewhich

    had

    previously

    marked the

    volumetric

    edge

    of

    the

    building,

    n a manner imilar

    to

    the southfacade

    (Fig.

    14).

    This

    change

    marks

    the lateral

    layering

    of

    the

    original

    volume

    which reads as

    one

    aspect

    of the

    transformational

    tructure.This

    volumet-

    ric extension

    seems

    purposely

    conceived

    as

    an element

    which

    does

    not

    carry

    cross

    the

    entire

    facade,

    in

    order

    o create

    a con-

    dition

    of shear

    (Fig.

    15).

    This

    condition

    allows

    a dual

    reading:

    eitherthe

    facade

    has

    been

    extended,

    n

    an additive

    manner,

    as

    a

    sequence

    of

    planes,

    or

    the outer

    edge

    has

    been

    eroded

    to reveal an internal

    "solid"

    volume

    (Fig. 16).There are several

    precedents

    for

    the

    particular

    hape

    of the

    north

    facade;

    one

    which

    could best be described

    as

    a

    bent

    plane.

    One

    would have to be

    Le

    Corbusier's

    building

    at the Weissenhof

    Siedlung

    (Fig.

    17).

    Cat-

    taneo's

    apartment

    Cernobbio

    (Fig.

    18).

    Terragni's

    use

    of this

    shape

    has

    an

    relationship

    to

    the

    structure.

    The

    bent

    plane

    works

    in

    two

    ways

    to

    articulate

    the

    inten-

    tion to contrast

    reading

    of

    eroded

    solid

    with

    sequence

    of

    spatial layers.

    a

    conceptual

    as a

    and

    with the surface

    The

    particular

    rticulation

    of this

    surface,

    the

    shearing

    condition,

    forces

    a

    second and

    corollary reading

    (that

    of a

    layering

    of

    planes)

    to

    assume

    an

    equal

    valence. The

    shearing

    condition

    is rein-

    forced

    by

    the

    narrow slot windows

    (Fig.

    20)

    which

    appear

    only

    in

    one

    bay

    and

    to-

    gether

    with

    the residual horizonal slots

    along

    which

    the

    solid

    seems to be

    shifted

    to a

    position

    to

    the

    northeast

    Fig.

    21).

    Again,

    both

    readings

    are reinforcedwhen

    the cornersof the

    north

    acade

    are

    exam-

    ined. The treatment

    f

    the northeast

    or-

    ner,

    in

    particular

    the

    placement

    of the

    windowswithrelation o the

    floor,

    auses

    the

    three-story

    olid to read as a

    plane

    pulled

    from the

    volume,

    adding

    another

    aspect

    to a

    planar nterpretation

    Fig.

    22).

    It is

    worth

    noting

    the

    horizontal

    banding

    of windows

    (Fig.

    23)

    on the north

    acade

    occurs

    midway

    between

    floor

    nd

    ceiling,

    and thus does not define the horizontal

    planes.

    This acts to

    suppress any

    reticu-

    lated

    column-slab

    reading.

    It

    is

    possible

    to

    interpret

    he east

    facade

    (Fig.

    24)

    as

    a datum

    plane

    on

    which

    the lateral

    layering

    of the

    volume

    from outh

    to

    north s marked

    (Fig.

    25).

    This

    facade also acts

    as a referent

    or the

    original

    conceptual

    solid,

    and can be

    seen

    as

    the inverse

    of the west facade

    which

    is

    essentially

    reticulated

    nd additive

    in

    na-

    ture. This

    datum,

    as

    compared

    with

    the

    datum

    of

    the

    entryplane

    of the

    Casa

    del

    Fascio,

    is

    not

    conceived

    of

    frontally.

    he

    dialectic is not revealedwithin he facade

    plane

    itself,

    i.e.

    the

    solid-cut-away ppo-

    sition

    with a reticulated

    structure,

    which

    occurs

    within

    each facade

    plane

    of

    the

    Casa del

    Fascio),

    but rather

    t

    the

    unction

    of two

    planes,

    at the corners. It is

    only

    on

    the

    oblique,

    where the

    corners

    are articu-

    lated as a

    meeting

    of

    planes

    rather han as

    an

    edge

    of

    a volumetric

    olid,

    that he sec-

    ond

    reading

    becomes

    apparent.

    Whereas

    in

    the Casa del Fascio the

    conceptual

    structure s articulated

    through

    the dia-

    lectic between eroded solid

    and reticu-

    lated

    grid,

    the dialectic

    in

    the Giuliani-

    Frigerio

    is between

    eroded solid and a

    sequence

    of

    planes,

    with

    a

    corresponding

    suppression of both reticulated and stri-

    ated

    readings.

    Thus

    while the Casa

    del

    Fascio

    suppresses

    the

    oblique,

    and the cor-

    responding

    iagonal

    structure or

    frontal

    e-

    lationships,

    he

    Giuliani-Frigerio

    emands

    the

    oblique."

    It

    is

    interesting

    o

    note that

    in both

    buildings,

    while

    there s an

    empha-

    sis

    on

    facade articulation

    s

    a

    notationfor

    the

    specific

    syntax,

    n

    neither case does

    the articulation

    arry

    hrough

    he

    building

    to a

    complementary

    rdering

    of

    the inter-

    nal

    spatial

    structure.For

    example,

    in the

    Casa del Fascio

    the

    layering developed

    from

    he front

    acade is

    partly

    erminated

    by

    the central

    space;

    the

    deep

    beams,

    which run in a single direction,are the

    only

    indication

    of

    the continuation

    f the

    planar

    layering

    hrough

    he central

    space.

    And

    while there

    is some

    marking

    f

    this

    internal pace on the facades of the Casa

    del Fascio (in the tripartiteABA facade

    structure), there is very little reciproca-

    tion from nside to outside in the Giuliani-

    Frigerio.

    This can be attributed

    o several

    factors. First because of thenatureof the

    program

    in

    the Giuliani-Frigerio

    -con-

    ceptually

    there

    are very

    few internal

    spaces;

    and

    second,

    because

    the specific

    syntax

    is

    concerned

    with corners

    and

    edges,

    with

    references

    o adjacent

    planes

    rather hanwith

    nternal-external

    layering;

    or lastly, t is possible that

    Terragni ould

    not

    manipulatewith

    facility

    he

    layering

    f

    internal pace (as opposed

    to his rather

    sophisticated layering

    n

    facade

    planes).

    The

    evolution of the east facade

    Ill

    ILIJcan

    best be seen

    in

    relation to the early

    studies.

    In

    Scheme A

    (Fig.

    26)

    the

    "east"

    --777717i

    facade s

    actually

    n

    the

    estI

    with

    he

    re-

    versal of the

    plan

    in

    Scheme B, it becomes

    the east facade. The

    particular size and

    -z

    disposition

    of the

    openings in this early

    study

    can

    be seen

    as

    similar

    in

    intention

    I..to

    thatof the

    northwest

    acade ofthe Casa

    del Fascio

    (Fig.

    27);

    i.e. a triparite ivi-

    sion

    and a

    positioning f windows in such

    26

    a manner s

    to reveal

    a latentreticulated

    30

    grid.

    The

    openings

    in

    the

    central

    bay

    of

    Scheme

    A

    quite

    literally ndicate the stair-

    way

    and the

    half-level hange in the floor

    plane.

    Since

    the

    particularform of these

    openings

    can be read

    also as having been

    cut from

    solid,

    a

    secondary interpreta-

    tion

    is also

    implied.

    In

    later

    schemes

    (Fig. 28),

    the

    reading

    of a

    tripartite eticulated grid is

    suppressed

    and the

    ambiguity is devel-

    oped

    between

    readings of eroded solid

    and

    planar

    layering.

    There are only minor

    adjustments

    from

    Scheme C to Scheme

    D.

    In

    Scheme

    D

    (Fig.

    29)the major openings

    are treated s continuousbands the

    27

    facade,

    giving

    n

    implied

    continuity

    o the

    plane

    (Fig.

    30).

    Even

    when there are iso-

    lated

    openings,

    as

    in

    the right-hand

    bay,

    they

    ontinue

    the

    implied ine of the band-

    ing.

    In

    this

    bay

    the

    windows

    are

    placed

    L7

    slightlyway

    rom

    n

    implied

    olumnine

    (Fig.

    31).

    This

    location relieves them of a

    --

    -

    possible

    interpretation

    s marking

    he

    col-

    T I

    umn

    line on the

    surface,

    thus

    sustaining

    suppression

    of

    a

    reticulated

    reading.

    Ear-

    --.

    C,

    a

    volumetric

    rojection

    is

    By

    virtue

    of

    this

    cutting,

    he

    projections

    thus have a

    primary

    olid

    as

    opposed

    to

    a

    planar

    reading,

    and a

    secondary

    dialectic

    of

    the

    two.

    Because

    these solids read

    as

    having

    been moved

    through

    membrane,

    this

    gives

    thefacade a

    planar

    quality.

    Fig.

    33).

    But

    these

    projections

    also

    provide

    the

    alternate

    reading

    for

    he facade

    by

    vir-

    tue

    of

    their

    placement

    in

    relation

    to

    the

    horizontal

    anding.

    These

    projections

    lso

    appear

    to have

    been

    pulled

    along

    the fa-

    cade leavingthe horizontal penings as a

    residue

    of

    their

    movement.

    Fig.

    34).

    This

    particular

    formal

    device

    while similar

    to

    the

    type

    of

    shift

    described

    previously

    on

    the

    north

    facade,

    seems to

    have

    as a

    source

    Cattaneo's track-like

    age

    in

    his

    building

    Cernobbio

    (Fig.

    35).

    Here

    there

    is

    no

    cage,

    but

    merely

    he

    use of

    a

    shear-

    ing

    to

    indicate a

    possible

    solid-plane

    am-

    biguity.

    The

    ambiguity

    s

    further

    eight-

    ened

    by

    carrying

    hefacade

    plane

    window

    banding

    across

    the solid

    projections.

    Thus,

    when

    viewed

    frontally,

    he

    facade can

    be read

    as a flattened solid.

    Even

    the

    box-like

    projections

    appear

    am-

    biguous. In one sense they lso seem to be

    flattened

    because

    of the

    particular

    win-

    dow articulation

    which

    appears

    to con-

    tinue

    the facade

    banding

    across the

    pro-

    jections.

    It s

    only

    when one

    moves to the

    oblique,

    either

    the southeast or the

    north-

    east

    corners,

    does the second

    implied

    reading

    of

    a

    planar

    layering

    become

    apparent.

    From

    the

    southeast,

    the solid

    ver-

    tical

    wall

    section extends as a

    plane past

    the

    vertical

    olumn line which can be read

    as a datum

    marking

    he corner of

    the

    in-

    ternal

    volume.

    (Fig.

    36).

    The balconies

    of

    the

    To arrive

    t

    this

    level of

    ambiguity

    on

    the east

    facade,

    Terragni

    s forced

    to

    mask,

    through

    he

    manipulation

    f the fa-

    cade,

    what is

    happening

    on the interior.

    n

    other

    words,

    to force a

    conceptual

    inter-

    pretation,

    ertain

    markings

    re

    necessary

    which

    obscure direct internal-external

    readings.

    This break

    with the then estab-

    lished

    canon of the

    modern

    movement

    mustbe

    considered

    as intentional

    n

    light

    of theargument eingpresented.

    The south and

    west

    facades are

    the most

    highly

    articulated;

    in

    a sense

    they

    can

    be considered

    the

    two

    "open"

    facades.

    To understand

    he

    south facades

    (Figs.

    38 &

    39),

    another

    comparison

    with

    the Casa del Fascio will

    be

    useful.

    The

    south facade has certain

    preceptual

    simi-

    larities o thesouthwestor

    entry

    acade

    of

    the

    Casa del Fascio

    (Fig.

    40).

    There

    is a

    similar

    tripartite

    organization

    with the

    solid

    portion

    f the facade reversed

    in

    the

    Casa del

    Fascio

    it is

    on

    the

    right,

    n

    the

    Guiliani-Frigerio

    t is on the

    left).

    How-

    ever,

    in the Casa del Fascio the actual

    structure

    the vertical and

    horizontal

    l-

    ements- are placed inthe facade plane.

    This

    does two

    things:

    testablishes the re-

    ticulated

    grid

    as one

    aspect

    of the formal

    dialectic

    and itestablishes the

    primacy

    f

    the facade

    plane

    as a

    datum,

    from

    which

    the

    layering

    of

    subsequent planes

    can be

    read. In the

    Giuliani-Frigerio

    here seems

    to be a conscious

    attempt

    o

    create,

    as it

    were,

    a

    shifting

    atum because of the dif-

    ferent formal structure

    being

    used. The

    solid vertical

    element of the

    facade,

    in-

    stead

    of

    being

    1:3 as

    in

    the

    ABA

    relation-

    ship

    of the Casa del Fascio

    facade,

    is re-

    duced to the

    width of

    one

    bay;

    and

    this

    element

    rises above

    the

    glass

    line

    to form

    a

    frame

    with the

    edge

    of the horizontal

    roof

    plane.

    (Fig.

    41

    ).

    In

    one

    interpretation

    his

    frame

    marks

    the

    edge

    of

    a solid

    which

    has

    been

    eroded

    away.

    In

    the

    other,

    he frame cts

    as a

    datum.

    Elements

    are

    projected for-

    ward

    and are

    recessed

    back from

    hisda-

    tum to

    mark

    a series of

    vertical planes.

    (Fig. 42). Here

    the columns are set back

    to

    mark

    one

    layer,

    nd

    the

    balconies pro-

    ject forward to mark another

    -

    in both

    cases

    the

    particular

    formal intention

    seems to

    be to

    suppress a

    reticulated

    ead-

    ing similar to one which occurs in the

    Casa del

    Fascio.

    Again, when the viewpoint

    shifts

    fromfrontal o oblique, the readings are

    changed. For example,

    whenviewed from

    the

    southeast it is

    not

    the line of

    the left-

    handvertical

    plane

    and the

    horizontal oof

    which read

    as the

    datum,

    but rather

    t is

    the

    line of

    the

    columns,

    which

    (Fig.

    43)

    from

    he oblique

    viewpoint,

    because it

    is

    the

    only

    uninterrupted

    ertical,

    becomes

    the primary

    eference.

    The

    west facade can be

    besttraced

    by

    an

    analysis

    of

    the

    plans,

    because

    pho-

    tographs

    of

    the

    actual facade are

    partially

    masked

    by

    a double

    row of low

    trees.

    (Fig.

    44).

    The

    important

    notation

    is

    again

    seen

    in

    the

    marking

    f

    the

    corners,

    where

    the

    intention o

    treatthis as an

    'open'

    fa-

    cade

    is

    most

    apparent.

    The dialectic of

    solid volumes and

    planar

    layering

    s

    less

    important

    han

    the

    ambiguity

    developed

    by

    the

    marking

    of the

    vertical

    layering

    (Fig. 45). On thenorthwest he line ofthe

    A

    similar

    ondition lso

    pertains

    on the

    corner which

    because of

    the

    placement

    of

    outriggers,

    tends to

    give

    the entire

    facade

    an

    'open'

    notation.

    In

    conclusion,

    two

    comparisons

    with the Case del Fascio are worthwhile.

    Both

    buildings

    are

    examples

    of

    the

    use of

    pictorial

    or

    conceptual ambiguity

    as

    a

    transformational ethod.

    n

    each case the

    particular

    use of form

    s different.

    Both

    buildings

    can be

    considered

    as

    basically

    externalized,

    nthattheir

    pe-

    cific

    marking

    works toward

    elaborating

    n

    external,

    context-oriented structure

    of

    space

    rather

    han to

    the

    marking

    f an in-

    ternal structure. n fact, in the Giuliani-

    Frigerio

    t s

    possible

    not

    only

    to

    say

    there

    is little internal

    pace,

    but also that the

    internal unctional tructure the

    layout

    of

    rooms,

    etc.

    -

    seems

    to derive little f

    its orderfrom he

    external

    acades-a

    fact

    which s substantiated

    by

    the innumerable

    room

    arrangements

    which exist

    for

    each

    of the

    four

    chemes.

    And,

    as has been said

    before,

    little of the internal structure

    s

    manifest

    on the

    projections

    and distor-

    tions of the facades. Another

    important

    difference s the

    conception

    of the

    rela-

    tionship

    between the

    observer and the

    building.

    Whereas the Casa del Fascio is

    conceived to be understoodprimarilyn a

    frontal ontext

    suppressing

    oblique

    read-

    ings

    forfrontal

    nes),

    the

    Giuliani-Frigerio

    demands

    both

    oblique

    and

    frontal rienta-

    tion;

    and because

    of

    the

    important

    f

    the

    corner articulations

    to

    the formal inten-

    tion,

    the

    oblique

    references

    seem

    to

    be

    preferred.

    his leads to a

    second

    distinc-

    tion between the

    two formal

    ystems.

    In

    the Casa del Fascio the

    frontal

    emphasis

    -

    the

    layering

    f

    space

    from

    frontal

    datum

    -

    is considered

    mainly

    in

    relation o

    the

    specific

    context;

    n

    the rela-

    tionship

    of the

    building

    to

    the

    adjacent

    piazza

    and to the

    cathedral

    (Fig.

    47).

    In

    the

    Giuliani-Frigerio

    he

    oblique

    emphasis is less clear and less well re-

    solved

    in

    terms of

    the immediate context.

    For

    example,

    if

    the north

    nd

    east facades

    are read as "solid" and

    the

    south

    and

    west facades are read as

    "void", there is

    a resultant diagonal

    established which

    could

    be said to

    respond

    to

    the

    existing

    site condition (Fig. 48). It is difficult o

    sustain thisargument o any extent

    if one

    returnsto the analysis of the particular

    marking f each facade. It is ratherbetter

    to say that the oblique and diagonal read-

    ings

    result from

    he particular

    yntax of a

    planar

    and

    volumetric

    mbiguity,

    han to

    load this

    building with arguments that it

    should not have to bear.

    Terragni'swork, and in particular

    the Casa del Fascio

    and the Casa Giuliani-

    Frigerio,

    eems

    important

    o an

    initial on-

    sideration of

    the use of

    ambiguity

    as a

    transformationalmethod,

    especially in its

    potential

    for

    relating

    different cales

    of

    physical

    environments.As

    has been

    Frigerio,

    since

    such

    a method

    was not

    necessarily

    a conscious

    intention

    of

    the

    design,

    it is not

    to be

    expected

    that

    relationship

    f

    would

    be

    and

    thus

    not

    capable

    of

    The

    relevance of the above discus-

    sion can

    be

    seen

    in

    the

    following

    terms.

    First,

    f

    t

    s

    accepted

    that he

    problem

    f

    a

    search

    for new

    shiftfrom n

    "object"

    to

    "relationship"

    orientation s

    one

    possible way

    to

    conceive

    of the

    prob-

    lem. Given such

    a

    change

    in

    focus,

    the es-

    tablishment

    of both a surface and

    deep

    level

    syntax

    s

    well

    as the

    development

    of

    transformational

    methods,

    which

    relate

    the

    specific

    forms o a

    series

    of

    formal

    ni-

    versals become

    necessary.

    The formal

    nalysis

    of

    the

    Giuliani-

    Frigerio

    has

    attempted

    to

    show one such

    method,

    involving

    the use of

    essentially

    pictorial

    means -the

    ambiguity

    of

    lay-

    ered

    planar

    space

    and volumetric

    space.

    Within

    the limits of

    this

    one transforma-

    tional

    device

    an infinite

    ange

    of

    specific

    forms

    can be

    conceived which

    have

    the

    possibility orrational

    interpretation

    ased

    on a limited

    series

    of

    formal

    universals.

    In

    a

    design

    process

    this

    type

    of

    formal n-

    alysis

    also

    remains

    imited,

    s the ntuition

    still

    plans

    a

    dominant role.

    Chomsky

    has

    said thatas

    long

    as

    a

    grammar

    emains

    at

    an intuitive

    r less than

    conscious

    level,

    many strategies

    remain

    unavailable to the

    user.

    Thus,

    an

    exploration

    f

    the

    realm of

    deep

    level

    syntax

    would be

    necessary

    to

    develop

    a

    finite

    structure f

    formational

    rules to which

    each

    specific

    syntactic

    structure ould relate.Rather

    han

    imiting

    the

    intuition,

    such

    an

    objective

    under-

    standingmight

    ead to

    freeing

    nd

    expand-

    ingof the role of the intuitionna rational

    design

    process.

    It

    is thus

    possible

    to

    think

    of

    the

    existing

    oeuvre of the

    modern movement

    in an analytical

    rather han an

    historical

    context.

    Inthis

    sense,

    it is possible

    to see

    the work of Leger and Gris,

    Mondrian nd

    Malevich, Le Corbusier and

    Terragni as

    having

    posited an intuitive

    ramework. he

    elaboration

    of this framework s a task

    which remains head.

    Mr. Eisenman is

    an architect. He is at

    present di-

    rector of The Institute

    for Architecture

    nd Urban

    Studies in New York.

    Much of the research on the work of Giuseppe

    Terragni was

    done in 1967 on a

    fellowship from

    the

    Graham Foundation for Advanced

    Studies in

    the Fine Arts.

    Previous to

    this

    fellowship, Mr.

    Eisenman had re-

    ceived

    two

    small research grants

    from Princeton

    University

    for summer

    work in

    Italy, on the same

    project.

    Most

    of

    the

    drawing of the plans, sec-

    tions, and

    elevations were

    done by

    three of Mr.

    Eisenman's

    former

    students:

    Russell

    Swanson of

    Princeton;

    Daniel

    Liebeskind

    of

    Cooper

    Union;

    and

    of The

    Institutefor

    Architec-

    ture

    and Urban Studies.

    original

    argument.

    3 Robert

    Slutzky,

    n

    a

    conversation,

    makes a clearer

    distinction n this context. He says a more precise

    comparison

    would

    be between

    Cezanne and

    Mon-

    drian,

    or in the case of

    Leger

    and

    Gris,

    only

    their

    earliest

    work. In

    their

    later

    work,

    both

    Leger

    and

    more

    specifically

    Gris

    initiatedtheir canvases with

    an a

    priori

    conception

    of

    geometric

    structures

    nearly

    devoid of ssociational references.Their con-

    cern

    with

    objects

    was

    only

    in

    the

    sense

    of

    object

    as

    type,

    as

    opposed

    to

    object

    with

    a

    specific

    mean-

    ing.

    Cezanne,

    on

    the

    other

    hand,

    begins

    with

    an

    object-oriented

    abstraction.

    Obviously,

    Mondrian

    stands

    in clear

    opposition

    to

    both

    approaches

    -

    painting

    completely

    non-referential

    tructures

    in

    no

    way

    relying

    on

    associations

    of

    a

    given

    object

    context.
