Basement Conversion Wimbledon London

Basements in Clapham, Battersea, London… It is possible to increase the size of an existing south London cellar to the size of the footprint of the entire building. Such projects require careful structural calculations and specialist underpinning techniques.

Suitability for a Basement

Clapham, Balham, Battersea in London are very suitable for a basement, but it is good practice to commission a geotechnical survey to ensure site suitability. Problems would not rule out a basement but are likely to increase basement excavation and waterproofing costs.
