Basement Conversions


Many homes, lucky enough to have a pre built basement or cellar, often will not give them a thought. They are considered cold, damp areas strewn with pipes and cables from poorly envisaged builds. Often, they will suffer flooding due to insufficient damp proofing or drainage.

What is often missed is the opportunity to modernise and convert these spaces into vibrant living areas creating a new dimension to your home.

We are able to offer a full service for converting your existing basement from providing top quality damp proofing and drainage remedies, the re routing of gas pipes, electrical cables and sewage pipes to the creation of a whole new living area unrecognisable from the original damp cellar!

A basement conversion can provide more new space per pound spent than most extensions.

Our team of project managers, builders, structural engineers, electricians and gas engineers will ensure that your existing property remains structurally sound and that a seamless integration of your new space is delivered.

All our work is backed by our Company Guarantee and the materials used (we use John Newton Membranes – the best in the industry) carry their own 30 year guarantee.

Please contact us for a no obligation chat to discuss the suitability of your home for this exciting option.
