Architectural & Interior Design in Mayfair.
Good building starts with good drawings. Our in-house architects and interior designers take a project in Mayfair from a first conversation to a set of drawings the council will validate and a builder can price, and because we are also the builder, the drawings are produced with construction in mind from the first sketch.
The design stage begins with a measured survey of the existing house and a conversation about how you live. From that we draw two or three options, develop the one you choose, and produce the planning application, building regulation drawings and interior specification: finishes, lighting, joinery, kitchen and bathrooms, all as one coordinated scheme.
We design to the policies of the City of Westminster from the outset, so schemes are not redrawn after a refusal, and we obtain pre-application advice where that would help. Many clients start with the design stage alone and decide later whether to build with us; the drawings are theirs either way.

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.
