Planning permission drawings, Listed Building Consent, and heritage-grade building regulations for Mayfair's Georgian townhouses, mews, and mansion flats. MCIAT chartered, fixed fees, Westminster heritage expertise built in.
Mayfair sits in the W1 postcode at the centre of the City of Westminster. The neighbourhood is London's most prestigious residential address — Georgian mansions, Regency townhouses, and private squares all sitting within near-complete conservation area coverage and extensive listing.
Mayfair Conservation Area: Covers the whole neighbourhood. Article 4 Directions remove PD rights. Heritage Statements are required for every application. Our MCIAT-chartered team prepares Mayfair-grade submissions with appropriate level of detail.
Private estates: Mayfair includes the Grosvenor Estate, the Portland Estate, and other private freehold estates. These estates apply their own design codes alongside Westminster's planning controls. We prepare schemes that satisfy both.
Listed buildings: A majority of Mayfair housing is listed — Grade II common, Grade II* and Grade I on premier streets. Listed Building Consent is routine. We coordinate with Historic England for higher-grade listings.
Mews houses: Mayfair's mews streets — Adams Row, Charles Mews, Mount Row — have particular design codes. Garage conversions, rooflights, and rear alterations all require planning permission and often estate consent.
