Princess Mary House

Princess Mary House is a tenement block of flats built between 1928 and 1930 as part of the Westminster Housing Scheme for the Grosvenor Estate. The design was by Sir Edwin Lutyens. The building is constructed of grey brick and white rendered chequerboard elevations, with grey brick and rendered access galleries to the rear courtyard. Stone dressings are used and the roofs are concealed. The architecture is in a stripped Georgian style, with decorative details concentrated on the entrance bay.

The building is symmetrical to Vincent Street and consists of six storeys. A broad central recess is blank except for central stairlights, flanked by projecting ranges each four windows wide, with one blind bay rendered as a chequer panel. The building has six-window returns and four-window south-facing ends to the shallow rear courtyard wings. A central channelled pier provides access to the stairs, featuring an archivolt arch under an open pediment and stepped parapet, set within a built-out ashlar screen wall, with four carved stone escutcheon panels above. Flush framed sash windows with glazing bars are set within the chequerboard pattern. Parapet copings finish off the facades. It is considered an imaginative Lutyens treatment of a typical London County Council housing block.
