NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle luxury refurbishment in Mayfair W1, under one contract. A full renovation runs £250 to £650 a sq ft, construction only. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Mayfair was laid out in the eighteenth century, largely by the Grosvenor estate.
Its brick and stone townhouses are now mostly apartments. Mansion blocks and mews sit between them.
A refurbishment here renews everything behind the walls. Wiring, plumbing, heating and ventilation all go in new.
Westminster now asks for retrofit first. Reusing an existing building is supported in principle.
We record the period fabric first. Then we design, price and build under one contract.

Further reading, from the journal
Does Westminster support refurbishing an old Mayfair building rather than rebuilding it?
Yes. City Plan Policy 43 puts retrofit first.
Reusing a building and improving its energy use is supported in principle.
Substantial demolition has to pass a sequential test first.
What is the Mayfair Neighbourhood Plan?
A plan written by the local forum and made by Westminster in December 2019.
It sits beside the City Plan when applications here are decided.
Its policies cover heritage, housing and the environment, among others.
Can I refurbish a listed Mayfair townhouse?
Yes, with listed building consent for work that touches its character.
Policy 44 asks for period detail to be kept, or restored where lost.
We record the fabric before anything is drawn.
Do I need the Grosvenor estate’s consent to refurbish in Mayfair?
Often, where the estate owns the freehold.
Its licence sits alongside planning and listed building consent.
We read the lease first, then plan the approvals together.
What does a Mayfair refurbishment cost?
Our full renovation band is £250 to £650 a sq ft, construction only.
Most Mayfair work lands in our super prime band, £500 to £800.
