Mayfair’s Georgian townhouses are now mostly apartments, with shops at street level. Mews houses sit behind the main streets. A whole house is rare.

Westminster counts Mayfair among its 56 conservation areas. A neighbourhood plan, made in December 2019, sits alongside the City Plan.

Policy 43 backs refurbishment and reuse. Pulling a building down means passing a sequential test first. So most Mayfair schemes rework the structure that exists.

Policy 44 asks that a listed building keeps its special interest. Cornices, doors and fireplaces stay, or return where they were lost. Officers expect a heritage statement explaining each intervention.

Above a shop, an apartment has no householder permitted development rights. A rooflight, extract duct or condenser each needs consent. Lateral works in a listed building usually need listed consent too.

What Westminster asks of a Mayfair scheme.

Council: City of Westminster, reading the December 2019 neighbourhood plan alongside its own.
Retrofit: Policy 43 favours reuse. Demolition must first clear a sequential test.
Listed buildings: Policy 44 wants period detail kept, and restored where it has gone.
Conservation: One of 56 conservation areas across the city.
Estate: Grosvenor holds much of the freehold, and its licence runs with consent.
