Design & Build in Mayfair.
Design and build means we take responsibility for the whole project, from the first sketch to the day you move back in. There is one contract, one programme and one person to call, and the people who drew the scheme are in the same office as the people building it.
For a house or flat in Mayfair that covers the measured survey, concept and developed design, planning and building regulation drawings, the applications themselves, construction by our own site team, the kitchen and bathrooms we supply, joinery, decoration and handover with a guarantee on the work.
The advantage is simple: nothing falls between an architect, a planning consultant and a builder, because they are the same team. Problems are solved on the drawing board rather than on site, and the price and programme are set before work starts.

Mayfair: the houses and the planning rules.
Mayfair is Georgian London at its grandest: the Grosvenor Estate's squares and streets, five-storey townhouses on Mount Street and South Audley Street, mews behind, and later mansion blocks and apartment buildings. Most houses are Grade II listed, the whole district is a conservation area, and the Grosvenor Estate exercises its own control over many properties.
We have fitted kitchens on South Audley Street, working with ebony veneers, Corian and Miele appliances in rooms with original cornices and shutters. Projects here are logistically demanding: restricted parking, timed deliveries, concierge buildings and neighbours who expect a quiet, tidy site.
The Mayfair Conservation Area covers the whole district.
Westminster City Council
Planning and listed building consent are decided by Westminster, with Historic England consulted on the most significant houses.
Grosvenor Estate
Where the freehold is held by the Grosvenor Estate, its own consent and design guidance apply in addition to the council's.
Basements
Westminster's basement policy limits depth and extent under gardens and requires a Basement Impact Assessment.
Approvals for design and build in Mayfair.
