Luxury refurbishment in Belgravia.
Listed stucco houses and lateral apartments, refurbished under one contract. Consent, estate licence and build, run by one team.
What a Belgravia house asks for.
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle luxury refurbishment in Belgravia SW1, under one contract. A full renovation runs £160 to £350 a sq ft, construction only. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Belgravia was built as one estate, and most of it still reads that way. White stucco terraces face private garden squares. Mews houses sit behind them.
The houses are tall and deep, often five floors over a lower ground. Many are now apartments, some running across two houses.
A refurbishment here is rarely just a fit-out. Services are renewed behind listed plaster. Joinery is drawn to match what survives. Windows and stairs are repaired, not replaced.
We design, price and build it under one contract. Our own quantity surveyor prices it open book.
What the council allows.
- Council
- City of Westminster. Kensington and Chelsea’s CL7 does not apply here.
- Conservation area
- Belgravia is a conservation area. Changes seen from the street need planning, and are judged against the whole terrace.
- Listed buildings
- Much of the stucco stock is Grade II listed. Listed building consent covers inside work too, such as plasterwork, stairs and chimneypieces.
- The estate
- Much of Belgravia belongs to the Grosvenor estate. A leaseholder usually needs the estate’s licence as well as the council’s consent.
- Basements
- City Plan Policy 50. One storey below the lowest original floor. It may run under no more than half the garden.

Refurbishment in Belgravia, answered.
Do I need listed building consent to refurbish a Belgravia house?
Usually, if the house is listed, and much of Belgravia is Grade II.
Consent covers inside work too, not only the front.
We survey the period fabric first, then draw around it.
Does the Grosvenor estate have to approve my works?
Often, where the estate is the freeholder.
A leaseholder usually needs its licence alongside the council’s consent.
We read the lease and the estate’s requirements before design starts.
Can I add a basement under a Belgravia house?
Westminster’s City Plan allows one storey below the lowest original floor.
It may run under no more than half the garden.
In a listed house, it must not upset the building’s original order of rooms.
Has NU worked under Westminster’s rules?
Yes. A Grade II listed apartment in Marylebone, and an apartment in Mayfair.
Both sit in the City of Westminster, like Belgravia.
What does a Belgravia refurbishment cost?
Our full renovation band is £160 to £350 a sq ft, construction only.
A super prime finish runs £500 to £800 a sq ft.
