Mayfair was laid out in the eighteenth century, largely by the Grosvenor estate. Its brick and stone townhouses are mostly apartments now, often above shops. A whole house is rare.

Westminster supports reusing a building in principle. So a Mayfair scheme usually keeps the shell and renews the rest. That suits design and build, where one team weighs fabric, services and cost together.

ARB-registered architects we partner with draw alongside our own designers. Matt Coverley, our in-house quantity surveyor, prices from those drawings, line by line. A budget estimate is typically with you inside seven days.

We refitted a Mayfair apartment room by room, with joinery by Cochrane Bespoke. Nearby in Marylebone, we renovated a Grade II listed apartment.

Conservation: Westminster has 56 conservation areas over 78% of the city. Mayfair is one.
Estate: The Grosvenor estate owns much of Mayfair. Its licence often runs with council consent.
