Conservation, renovation and regeneration of a Grade I listed Modernist landmark (by Wells Coates, completed 1934) that had in recent years fallen into an acute state of disrepair

The scope of works comprised comprehensive rehabilitation of the reinforced-concrete envelope and restoration of the original facade colour (a pale pink); replacement of asphalt membranes; major upgrade of insulation values; renewal of wall, ceiling and floor finishes and windows and doors; and refurbishment of light metalwork elements and fitted joinery wherever possible, and replacement to match original where not.

While the original plan layout of the units has been retained throughout, minute dimensional adjustments have been made to accommodate new requirements, such as fridges and washing machines. Mechanical and electrical services have been completely reengineered to comply with current standards, but in such a way as to be consistently disciplined by architectural conservation constraints – likewise the integration of new communication, signage and security installations.

The scheme now provides 25 flats under shared ownership exclusively for key workers, with 11 further flats being sold on the open market.
