Covering Altrincham, Bowdon and Hale Barns and the surrounding area — period homes, established family houses and modern builds.
Altrincham
Cube Lofts & Extensions is a builder in Altrincham, and it is our home patch. We are a family-run building company based here, specialising in loft conversions, house extensions, garden rooms and garage conversions across Altrincham, South Manchester and North Cheshire. Altrincham has a real mix of housing, from large period and Victorian properties through established family homes to high-specification modern builds, and that blend means steady local demand for loft conversions that add a bedroom or office, and extensions that open up kitchens and living space to suit the way families live today.
Across Altrincham we carry out loft conversions, house extensions, garden rooms and garage conversions, with the owners on site for every project. As this is our base, turnaround on surveys and quotes is fastest here. With 25+ years of combined construction experience, a small focused team taking one or two projects at a time, and every relevant job signed off to the latest Building Regulations, you get honest advice and quality workmanship from start to finish. We are members of the Federation of Master Builders, fully insured and VAT registered.
