NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle house and kitchen extensions in Mayfair W1, under one contract. A rear kitchen extension typically runs £160k to £250k. A side return extension typically runs £140k to £220k. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Mayfair’s Georgian houses mostly hold flats now, many over ground floor retail. Whole houses are scarce.

That rules out the usual rear garden extension. There is seldom a garden to build on.

What works is lateral. An apartment takes in space beside it, through a party wall.

Mews houses behind the main streets are the other route. Their gains come from the roof or a reworked plan.

Westminster’s Policy 43 favours working with the building you have. Policy 44 guards period detail such as cornices and panelling.

What the council allows in Mayfair.

Council: City of Westminster, alongside the Mayfair Neighbourhood Plan made in December 2019.
Reuse first: Policy 43 favours adapting a building over replacing it.
Period detail: Policy 44. Listed rooms keep their special interest and period detail.
Roofs: Roof extensions are refused on complete terraces with largely unaltered roof lines.
The estate: The Grosvenor estate owns much of Mayfair. Its licence often sits beside consent.
Party walls: Opening a party wall is party structure work. Notice goes two months ahead.
