Basement Conversions

Refurbishing and Renovating existing Basements or cellars in Period properties can extend the living space and is often more cost effective than extending the building. We have much experience in converting damp, dark cellars into fantastic spaces, for additional living areas such as, cinema rooms, games rooms, snugs, dens, guest rooms, additional utility, kitchens or even swimming pools.
