The Project


39 Great Cumberland Place is part of The Portman Estate which covers 69 streets, 650 buildings and four garden squares in Central London. Built originally in the 1800s, this Listed building was bombed during the Second World War and was rebuilt in the 1950s using part concrete frame and part masonry construction, which is unusual for a property of this type in this area.

PBC Scope


PBC was appointed to provide Contract Administration and Project Management services for the internal and external refurbishment of 5 flats and the common areas in the building, which included upgrading the EPC rating for each apartment.

The project included layout reconfiguration of the interior spaces, a full refurbishment of all the flats, external repairs and redecoration, replacement of existing roof coverings, installation of a new external staircase to provide dedicated access to the basement area, external landscaping to the rear courtyard and the replacement of the aging lift.

The client’s brief was to improve the energy efficiency of the building whilst keeping the buildings historical character intact. This was achieved by installing insulation to the roof and external walls, the installation of double-glazed windows to the rear elevation and new multi-pane sliding timber sash windows to the front elevation with secondary glazing. The building is now heated entirely using electricity rather than gas.

The works took approximately 12-months to complete and, now that the works are completed, the EPC rating of the apartments has been upgraded from their original D level to C.
