EXPANDABLE MODULAR TEMPORARY HOUSING

Additional options for FEMA temporary housing to serve as building blocks for permanent housing



6-04-11


The following recommendations are variations of some of the products developed as part of FEMA’s Alternative Housing Pilot Program as implemented in Mississippi as the Mississippi Cottage Program. While maintaining many of the basic structural elements of certain Mississippi Cottages units, designed to withstand 150 mph winds, the recommended modules are simplified and designed specifically to be expanded for use as permanent housing after the temporary use period.

Address FEMA IA challenges:

•When the time required to repair or rebuild permanent homes will be protracted

•When placement of traditional manufactured housing may be unacceptable to the community

•Leverages FEMA IA investment in temporary housing to accelerate the development of permanent housing and shorten the temporary housing period


•Initial utilitarian design clearly understood to be temporary unless expanded and pitched roof added

•Generates less of a false sense of permanency

•Provides building blocks for future long-term housing



•Systems-built for rapid deployment

•Designed to meet 150 mph wind speeds with Safe Room potential

•Designed to meet State modular standards for maximum flexibility to convert to permanent housing

BASE MODULE2 BR – 1 BA 738 SF Plus Porch14’ X 60’ O.A.

Box-like structures with pre-framed door or hall openings facilitate future expansion/combination

•Parapet designed to support future pitched roof of 7 in 12 or greater.

•SPF flat roof highly energy efficient. Insulation remains after pitched roof is added.


1 BR 1 BA STUDIO MODULE313 SF Plus Porch14’ X 28’-2.25” O.A.

•Larger than a FEMA trailer (240 SF) but smaller than the current Park Model (387 SF)

•Open plan similar to extended-stay hotel studio suites offers greater flexibility to serve as expansion module for base unit

•Standard room dimensions accepts conventional furniture


•Provides opportunity for affordable housing organizations to leverage FEMA IA investment by converting temporary housing modules into permanent housing that is indistinguishable from conventional housing

•Modular approvals would be predicated on expansion and the addition of a pitched roof within a specified period


CONVERSION TO PERMANENT HOME

•Basic flat-roof modules offer potential for great architectural variety at conversion by constructing the permanent roof and porch at a later stage

•Pre-engineered designs for additions, roofs and porches should be provided in advance


•Without the pitched roof initially, modules with higher ceilings and transom windows can still be easily transported

•Taller facades enhance the exterior building proportions and permits more options for porch design


3 BR 2 BA 1071 SF PERMANENT UNIT2BR 1BA BASE WITH STUDIO28 2 1/2’ X 60’ O.A.

•Classic cottage style prevalent throughout the United States can be adapted to regional vernacular

•Indistinguishable from conventional housing

•Fits on typical 50’ x 100’ Lot

PERMANENT CONVERSION



Initial Limited-Production Proof-of-Concept Pilot

•Target non-profit housing developers such as Habitat for Humanity with clear capacity to complete conversion to permanent use

•Resident must be qualified survivor

•Provides model home for securing community buy-in

•Could be stick-built for proof-of-concept

•If stick-built, provide funding to Habitat equivalent to cost of 1 FEMA Manufactured Home and two Park Models for full build-out of 3-BR +Den/4-BR permanent home. (1 Base module plus 2 studio modules)

•Steel transport frame removable for placement on permanent foundations where zoning mandates “off-frame” modular

•Permanent foundation system subject to site conditions

•Steel-pier foundation system likely to be easiest for conversion from temporary to permanent.

Permanent Foundations

2 BR 1 BA DUPLEX758 SF each

•Two Base Modules Combined

•More efficient use of land and infrastructure

•Excellent product for affordable and senior housing

•Requires a portion of the 2BR-1 BA Base Modules to be mirror imaged plans
