Planning permission and listed building consent achieved for Cliveden Place basement extensions, Belgravia


Scott Brownrigg's planning and architecture teams have achieved planning permission and listed building consent on behalf of BlackOnyx Developments Ltd for new basement rear extensions within a Grade II listed building located a short walk from Sloane Square in Westminster.

The five storey family home, which forms part of a Georgian terrace of listed properties in Belgravia Conservation Area, is to be redeveloped to provide a media room and gym within a new basement level, together with extension at lower ground, ground and first floor levels to improve the living and sleeping accommodation. Planning Officers concluded that the design was acceptable in terms of planning policy and would not affect the amenity of neighbouring properties.  The members on Westminster’s Planning Committee voted unanimously to approve the proposals.

However, looking ahead Westminster is set to tighten up its planning policies on ‘subterranean development’.  The draft City Management Plan proposes to limit basement extensions to 50% of the garden area. The Royal Borough of Kensington and Chelsea is also considering revisions to planning policies on subterranean development following a substantial increase in the number of applications for these developments in recent years accompanied by a reported increase in the number of complaints from local residents relating to disturbance and other impacts. Developers seeking basement extensions in Central London and elsewhere are advised to monitor closely the changing planning policy on this topic in coming months in order to secure the best value from developments.
