Grosvenor Square Mansion

Location

Mayfair, London

Scope

Full interior architecture and furnishing of a mansion apartment, 8,200 sq ft

Duration

21 months

Four decades of subdivision had turned a single 1920s enfilade into a warren of smaller rooms. We removed the partition walls and restored the original 40-foot run the length of the piano nobile — the apartment's real proportions were still there, just built over.
