A full refurbishment of a private apartment on Cadogan Square, in one of the late-Victorian red-brick mansion blocks that line the square. The client had taken on the apartment as a long-term London home and asked for two things: bring it back to the standard the original architects intended, and make it work for the way the family actually lives now. The building is listed, the interiors are protected, and almost nothing could simply be removed.

The work ran through every room. Original cornices, dentil mouldings, panelling, shutters and skirtings were restored or replaced in matching profile where lost. New oak floors were laid through the reception rooms; services were renewed quietly behind the historic fabric. The most significant single piece is a set of full-height bifolding doors between the two principal reception rooms — solid panelled timber, drawn so the four leaves fold flat into the reveals when open and read as part of the wall when closed. Open, the two rooms become one space the length of the building. Closed, each is complete in itself.
