Many clients arrive wanting to replace a tired villa outright. In Westminster that is an uphill case. The City Plan treats the existing building as a resource.

Policy 43 puts refurbishment first. Substantial demolition must pass a four step sequential test. A Pre-Redevelopment Audit sets out the evidence, room by room.

So we test the keep option properly before anyone draws a new house. Often a deep retrofit, a rear wing and a lower floor deliver the brief.

Below ground, Policy 50 permits a single storey under the lowest original floor. Half the garden at most may be used. A metre of soil and drainage go on top, more near trees.

Part of the district became conservation area in 1967. There, Policy 44 asks every change to preserve or enhance its character. Stucco detail, boundary walls and front gardens all count.
