Many stone terraces in Bradford, Halifax and Huddersfield have a cellar with real potential. With the right waterproofing, a lightwell and a proper stair it becomes a dry, warm room.

Basements are the one job we will not put a number on without seeing the house. Head height, damp and access change the number too much. We survey, then draw, then price.

Basement conversions: questions people ask

Will a converted cellar be dry?

Yes, if it is waterproofed properly. We use a cavity drainage membrane system with a sump where needed, which carries its own guarantee alongside ours.

Do I need planning permission for a basement?

Converting an existing cellar usually does not, unless you change the outside of the house. Lowering the floor or digging out a new basement is a bigger job that may need an application and a party wall agreement.
