Frequently asked about basement conversions
In most cases, converting an existing basement or cellar doesn't require planning permission, as it's typically classed as a change of use. Excavating a new basement is more likely to need approval. We'll confirm what applies to your property.
Most basement conversions take between 8 and 14 weeks, depending on the scope of excavation and waterproofing required.
We install certified waterproofing systems designed to meet British Standard BS 8102, with drainage and sump pumps where needed to keep the space permanently dry.
