December 2019: Mayfair Neighbourhood Plan made
Policy 43: Reusing the building comes first

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle mechanical, electrical and plumbing in Mayfair W1, under one contract. MEP is priced from the drawings, after a survey of what is there. Call 020 7731 6841, and a budget estimate typically follows within seven days.

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

Above a shop, services share the building with a business. Extract, drainage and fire separation all meet in the same risers. We map who owns each one before design.

Westminster’s Policy 43 supports refurbishing and reusing existing buildings. Better heating, lighting and controls fit that well. Policy 44 asks work to a listed building to keep its special interest.

A pool hall here must duct to the outside through the existing building. The same thinking applies to cooling and kitchen extract. Routes are found inside, not added to the facade.

We fitted out a 1,500 sq ft apartment here, finished in 2021. Living, dining and kitchen share one room under tall bay windows.
