The client acquired an upper-ground floor flat in a white-stuccoed Grade-II listed townhouse built in the 1860s on Queen’s Gate, opposite the Natural History Museum, in South Kensington. While the flat featured four-metre-high ceilings and period mouldings in good condition, it was damaged by decades of unsympathetic transformations.
We proposed to restore an arched passage between the front and rear rooms. This archway had been walled up and the rear room’s historical ceiling concealed behind a suspended ceiling of no utility. By reopening this arch, we were able to create an open-plan living and dining room, bringing daylight to a kitchen which previously had none and gaining a metre in ceiling height. Around the new kitchen by Tom Howley, we designed clerestory partitions which the conservation officer appreciated as they revealed the original undivided volume of the rear room. These glass partitions are fire-rated to isolate the flat’s entrance from the other rooms, as required by the Building Regulations.
We applied for planning and listed building consent with the Royal Borough of Kensington and Chelsea and received permission in April 2025 on the first attempt. Construction began in September 2025 and ended in May 2026.
We also brought daylight and air to a new shower room by reopening a large sash window which had been inexplicably walled up. We relocated a second shower room and laundry room under the communal stair. C.P. Hart selected the shower room fixtures.
In order to have an oak parquet while meeting the Residents Association’s acoustic requirements, we contracted the Belgian company CDM Stravitec to install a 10-cm thick raised floor throughout the flat, consisting of rubber blocks, aluminium channels and two layers of oriented strand boards. We replaced the single-glazed sash windows and French door with new ones made of timber and slim-line double glazing. This made the flat more energy-efficient and quieter.
The oak floor, white walls and uplighting bring visual unity and calm to the flat. The clerestory partitions let eastern and western daylight traverse the front and rear rooms. We regilded a part of the cornice to restore this touch of warmth and sparkle.
