142 Bermondsey Street is a corner building in the heart of the Bermondsey Street Conservation Area, Southwark, London. The project involved the conversion, refurbishment and extension of an unlisted postwar steel frame warehouse, shop and flat. The design maximised the development potential, retaining the commercial use class, yet providing three unique urban residential units, achieved through increasing the height to introduce a roof top penthouse and creating a three storey live / work unit to the rear. The scope of the project included both the architecture and the interior design.
