Welcome to this public consultation event for Phase 3A of the Chelsea Barracks scheme.

Ben Pentreath & Associates is a small, busy architectural practice based in central London and have been contracted to design the first 2 buildings of Phase 3A of the development.

The practice is interested in demonstrating that modern, sustainable design can be seamlessly incorporated within traditional architecture.

They are committed to providing an excellent service and to designing buildings that are long-lasting, beautiful, and robust.

Ben is best known for his traditional design but the firm enjoys working in a more contemporary idiom where it is appropriate for the site or client.

Introducing the Team

Project Blue Ltd and Project Blue Developments Ltd are the owners of the Chelsea Barracks site.

Soundings are community engagement consultants and act as an impartial voice in the planning and development process, engaging with the local community to inform the masterplanning process and to ensure that local stakeholders are fully engaged in the dialogue. They have been involved in the project since August 2009.

Current Activities on Site

Site Preparations

Boundary obstruction removal

To date the site works have included:

• The completion of the demolition of existing above ground structures on site.

• Partial demolition of existing electrical substation structure.• Realignment of hoarding and the closure of footpath on the

site side of Ebury Bridge Road. The footpath will remain closed for the remainder of 2014 to allow for the removal of existing structures and to carry out groundworks and secant piling at the boundary of the site.

• Tree protection works on Chelsea Bridge Road, including the removal of some trees in agreement with Westminster City Council.

• Ongoing chapel maintenance works will be carried out to help protect and restore the Grade II listed structure.

• Crushing of demolition material for recycling and reuse on site.

The removal of existing structures above ground level is largely complete. The next phase of the Site Preparation works has now commenced. Careful consideration has been given to the methods that are to be adopted, with the aim of ensuring the minimum impact on residents and businesses adjoining the site, as well as ways that meet strict health and safety standards.

Methods of work

To allow the future retaining wall (see map above) to be built with minimal impact on local residents, the contractor, Keltbray, is currently removing all underground structures that lie within 1m of the site boundary. The method being used involves digging exploratory trial pits to locate obstructions and structures, which are then partially demolished up to 1 meter away from the boundary.

This method ensures that when the retaining wall is being constructed, it can be done with a much lesser impact, than had other processes been adopted. When the retaining wall is completed, any remaining underground obstructions can be removed and taken to another part of the site where they can be demolished without having an adverse impact on local residents.

Reserved Matters: An Explanation

Phases of Construction

The diagram above shows the various phases of the project which will be completed in an ongoing, overlapping process. It will start with Phase 1 on Chelsea Bridge Road/Pimlico Road and working towards Ebury Bridge Road.

Westminster City Council has granted consent for Phase 1 and a decision is expected soon for Phase 2. Phase 3A is expected to be submitted to WCC in August 2014.

There is a target to appoint a building contractor towards the end of 2014 who will work with PBDL to construct the basement and superstructures beginning in 2015 and delivering the fi rst 2 phases in late 2017 or early 2018.

Outline planning permission was granted by Westminster City Council in March 2012 for housing, retail, community and leisure uses with a health centre and sports centre. A prescribed range of residential units, fl oor areas, heights, and building footprints are defi ned within this permission in an agreed overall layout. The principal vehicular access points into the site and basement car parks, pedestrian access points and the landscaping of the publicly accessible areas of open space are also fully consented.

The design, appearance and precise architectural details within the defi ned dimensional parameters are “reserved matters” for subsequent approval, as are the remaining aspects of landscaping and access arrangements. Listed building consent

was also granted for limited alterations to the metal perimeter railings to form new pedestrian and vehicular access points.

The sketch design proposals shown at this exhibition identify emerging ideas that will be developed into the reserved matters applications seeking approval for Phase 3A buildings. Each phase of future development will require its own application for approval of the reserved matters dealing with the design appearance of the buildings.

Reserved matters applications have been submitted to Westminster City Council for Phase 1 and 2 of the development. An overview of both are shown at this exhibition.

Design Statement - Ben Pentreath & Associates

Precedent Images

The Phase 3A building occupies an important location in the new Masterplan, both in terms of its position at the termination of the vista from Chelsea Bridge Road, and the fact that it fronts the public square around the Garrison Chapel.

It is situated to the east of Garrison Square and the Listed Garrison Chapel. The scale and character of the Block 10 building in particular needs to respect the scale of the chapel, through both form and material, whilst providing a public building

The images below are examples of the precedents Ben Pentreath & Associates have studied to help inform their designs.

�is building occupies a pivotal location in the Phase 1 Masterplan. It forms an eye-catcher at the end of the Productive Garden and links the long vista to Chelsea Bridge Road with Ranelagh Grove and Pimlico beyond.

Relatively diminutive in size, we were concerned to give the building su�cient scale and distinctive form within the scheme as a whole. We have, therefore adopted a double-height arched form. An open arcade at the southern end forms an area for fruit and vegetable sales. �e restaurant faces the square itself.

�e building will be constructed of non load-bearing brickwork that is inspired from Sir John Soane’s stable block at the Royal Hospital. �is brick language is extended to create a series of monumental vaulted domes inside and out.

that faces onto a new public space of signifi cant scale within the development and street pattern as a whole. The intention is to create a form of building that respects the setting of the chapel without competing with the building either in form, detail or scale.

Block 9, the mews house, is located discreetly behind Block 10 and forms a continuation of the mass of the block 10 elevation, to provide a cohesive appearance.

The overall Chelsea Barracks Site is located adjacent to two conservation areas, with the Grade II Listed Garrison Chapel immediately adjacent to the Phase 3A site. To the north, the spire of the church of St. Barnabas Pimlico is a significant local landmark. The parameter plans respect the importance of the spire within the structure of the Chelsea Barracks Masterplan and it will be clearly visible above the roof of Building 10 as a terminating feature to the Entry Square, as shown in “View A” to the right.

The design of Block 10 has been developed with this proximity in mind at all times. The importance of the chapel as a heritage asset for the site demands a building that provides a restrained and well-considered background; that has a scale and presence of its own without competing with the language of the arcaded Romanesque 19th century detailing of the chapel. The brick and arcaded language of Block 10 was developed in direct response to the chapel.

Design considerations

Height, context and scale

The parameter plans allow for a 2-storey building at this location within a restricted height, surrounded by taller blocks. The designers have considered that the form should be treated as a single storey building with a high ceiling. In so doing the elevations read as having a larger scale, responding simultaneously to the important location within the masterplan and to the more domestic streets beyond.

Though limited in height, the building derives architectural presence from the scale of the repetitive brick arcade. By effectively creating a single storey building within a parameter plan that allows for two-storey development, the scale of the building is sufficient to respond to its position within the masterplan as a whole. The open arcaded bays at the southern end of the building will create areas of shadow further emphasising this scale when viewed from a distance.

Closer-to, the mass of the building is given texture and fine-scale by use of detailed brickwork and glazing.

The approved parameter plans allow for a two storey building at Block 10, and a single storey building at Block 9. Both buildings have a single storey basement (to allow ground water to reach the existing retained tree at the Garrison Chapel).

It is intended that Block 10 will be used as a delicatessen/café and restaurant, and Block 9 will be residential. The entire scheme is compliant with the parameter plans, with the roof plan of the Block 9 Mews House situated below the parameter line, which rises at a 22 degree angle from the boundary wall with Bloomfi eld Terrace (see drawing B-B right).

The services for the back of the house, the restaurant and deli is provided in the basement.

Phase 3A

Temporary use

For an initial period of up to 5 years, it is intended to use both buildings as a temporary marketing suite and sales show apartment for the development. It is intended therefore that two separate applications for Blocks 9 and 10 will be submitted in Summer 2014; one seeking permission for the permanent use and one seeking permission for temporary use as a marketing suite and show home.

The design of the structure has been considered for the long term use, and the temporary uses are being designed to fi t within this permanent structure without affecting the external appearance of the buildings.

It is likely that this will be the fi rst building to be built on the Chelsea Barracks site and will be complete whilst large amounts of excavation and basement construction are still ongoing.

To provide necessary access to the building it is proposed that the Ranelagh Grove access will be reinstated temporarily. The numbers of trips allowed to the site via this gate will be restricted and as soon as access is available from Chelsea Bridge Road, all visitors will enter via this route and the Ranelagh Grove access will be closed.

The principle façade material for Block 10 will be brick. The material responds to the Garrison Chapel and to the domestic architecture of Ranelagh Grove and Bloomfield Terrace; locally it draws from the restrained arcaded brick architecture of the Soane Stables at The Royal Hospital and Duke of York’s Barracks. The choice of material provides subtle but considered contrast to the Stone facades of Blocks 4 and 5, designed by Paul Davis & Partners, immediately to the south of the Phase 3A site.

Stone detailing is provide in a pale grey granite plinth and small amounts of limestone detail at the oculus (circular opening) and façade detailing of Block 9. It is proposed that bronze will be used for doors and windows. A flat lead roof is proposed for Block 10 and a green roof system for Block 9.

These are natural, traditional materials that will age and weather beautifully.

The designs show Paul Davis + Partners’ rigorous and logical design approach. This is created with reference to the vernacular of local architectural norms which gives general proportions of widths, floor heights and the distinguishing modules of local buildings.

Using the local vernacular to inform the secondary elements of the elevation such as glazing and the ratio of void (windows and doors) to solid has helped to ensure that the designs are appropriate and in keeping with Georgian London architecture. To build on this, the architects have examined and experimented with various architectural embellishments, to introduce a richness to the façade.

Block 5 facing the Square in front of Phase 1 Apartments consists of six, approximately 10 metre wide houses with an atypical end house occupying a triangular site to the northwest. As expressed in the façades of the houses in Block 4, the modulation of a base, middle and top of the typical Georgian house is reflected in the design.

The windows to each level have a hierarchical expression, typical of a Georgian façade of this height, with the first floor expressed as a piano nobile, enhanced by a moulding above the window and balconies with handcrafted bronze feel railings varying slightly in detail to express individuality. All the window reveals are finished in a limestone with a slightly enhanced level of fossilisation as for the houses in Block 4.

Block 4 comprises of six houses, five of which are typical, with a pavilion at the end of the terrace, on the northern side giving way to the square that accommodates Garrison Chapel. Each terraced house has an approximate frontage of 8.5 metres and a building depth of 15 metres.

The width of the house allows for a typical three bay window modulation. The bronze effect framed windows to each level are expressed differently in size and setting. Typical of a Georgian façade of this height, the first floor is expressed as a piano nobile, enhanced by a moulding above the window and balconies with handcrafted bronze effect railings. A bronze effect downpipe is set in a recess in the stone façade to emphasise the individuality of each unit within the entire architectural ensemble.
