NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle luxury refurbishment in St John’s Wood NW8, 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.

St John’s Wood was laid out as villas in gardens, rather than terraces.

Most of it has been a conservation area since 1967.

Westminster now puts retrofit first, and favours keeping a good building.

Substantial demolition must pass a sequential test, backed by an audit.

So we renew the house we have. Structure, services and rooms, under one contract.

Will Westminster let me demolish and rebuild in St John’s Wood?

It is hard. Policy 43 puts retrofit first.

Substantial demolition must pass a four-step sequential test.

Refurbishing the existing villa is supported in principle.

Does retrofit help a heritage application in St John’s Wood?

It can. Westminster gives significant weight to keeping the building.

Harm to heritage must still be avoided or kept to a minimum.

We set that out in a Retrofit Plan.

Is there a St John’s Wood Neighbourhood Plan?

No plan has been made. Work on one was paused in 2017.

Decisions follow Westminster’s City Plan and the conservation area audit.

Can I add a basement when refurbishing in St John’s Wood?

Usually, under Policy 50. One storey below the lowest original floor.

It may cover no more than half the garden.

At least one metre of soil goes back on top.

What does a St John’s Wood refurbishment cost?

Our full renovation band is £250 to £650 a sq ft, construction only.
