Builders and renovators in Clapham.
The large Georgian and Victorian houses around Clapham Common are some of the most extended and refurbished homes in South London. CAP designs and builds extensions, lofts, basements and full refurbishments across Clapham, with one team from planning through to aftercare.


What a project in Clapham usually involves.
Large parts of Clapham are covered by conservation areas, where external changes such as roof extensions, replacement windows and demolition are more tightly controlled than elsewhere.
The properties we are asked about in Clapham are mostly Georgian and Victorian houses around the Common, and terraces in Old Town and Abbeville Village. Around Clapham Common, Old Town and Abbeville Road, the character of the street shapes what can be built, and we design to suit it.
Planning applications in Clapham are decided by Lambeth Council, with streets west of the Common falling under Wandsworth. Whatever the project, we check which consents your property needs before recommending any spend on drawings.

Do you work in Clapham?
Yes. Clapham (SW4) is about 3 miles from our base on Mitcham Lane in Streatham, and the work we are asked about there is mostly on Georgian and Victorian houses around the Common, and terraces in Old Town and Abbeville Village.
Do I need planning permission to extend or alter a property in Clapham?
Often, yes. Large parts of Clapham are conservation areas, where roof extensions, side extensions, cladding and demolition that would be permitted development elsewhere need a planning application, and some streets have Article 4 directions that bring windows and front elevations under control as well. Flats and maisonettes need permission for any extension. We check the status of your address before design work starts.

Lambeth Council, with streets west of the Common falling under Wandsworth. Building regulations approval can come from the council's building control team or from a registered building control approver, and we arrange whichever suits the project.
