What we build
BUILDING WORK FOR HOMES AND BUSINESSES.
From a single-storey extension to a full commercial fit-out, we take on the structural and finishing work ourselves. If a job needs a specialist trade, we manage them so you deal with one company.

PROJECT 018Two-storey rear extension
Featured project · Residential
A TWO-STOREY EXTENSION, BUILT TO MATCH.
A family home needed two more bedrooms and a larger kitchen. We built a two-storey rear extension in matching brick, tied it into the original roofline and kept the family living in the house throughout.
