St John’s Wood is villa country. White stucco houses stand detached or in pairs, with real gardens. Families live in houses more often than flats.

That makes rear extensions and basements realistic, unlike much of Westminster. Mansion blocks closer to the main roads are the exception.

Rebuilding is harder. Westminster puts reuse first, under Policy 43. Substantial demolition faces a four step test, shown in a Pre-Redevelopment Audit.

Below ground, Policy 50 allows one storey under the lowest original floor. It may cover no more than half the garden.

Our nearest comparable work is a North London house of 3,500 sq ft. We reconfigured its structure and fitted it out.

What the council allows in St John’s Wood.

Council: City of Westminster, not Camden. Its City Plan was revised in January 2026.
Retrofit first: Policy 43 makes reuse the priority. It is supported in principle.
Demolition: A four step sequential test applies, shown in a Pre-Redevelopment Audit.
Character: Policy 44 asks work to preserve or enhance the conservation area, designated in 1967.
Lower floors: Policy 50 allows one storey below the lowest original floor, under half the garden.
