First look at Bell Phillips' east London housing retrofit
Bell Phillips Architects has released these photos of its £8.5 million, RIBA competition-winning retrofit of a housing estate in Plaistow, east London
The practice managed to reduced energy consumption in a typical 67m² two-bed flat on the Brooks Road Estate by 62 per cent and heating costs reduced by 55 per cent.
The work, which included extensive internal and external refurbishment of nearly 200 existing post-war low-rise homes, was carried out in five phases over a period of seven years with the final stage having just completed.
Shortlisted for last year’s 3R Awards, the project was part of a wider estate renewal which replaced existing post-war buildings with new-build terraced houses.
The architect’s view
Due to the various challenges presented by the different buildings, each phase was addressed as a separate project with a particular response to the challenges presented. As a result the project is made up of a collection of buildings which are tied together by consistent themes but offer variation and richness.
From the outset and throughout the process we worked in close consultation with residents, stakeholders, contractors and the local authority to provide a series of improvements at a range of scales, from estate-wide improvements such as the redistribution of public and private amenity space to small-scale proposals such as the design of new entrance porches for individual houses.
