Extensions, refurbishments and structural improvements across the post-war housing estates of the Somer Valley.
- Free site visit
- Fixed written quote
- Written workmanship guarantee
House extensions in Bath, Trowbridge and across BANES — from a side-return on a terraced street to a double-storey rear build. We handle planning drawings, structural steel, groundworks and Building Control in one fixed-price contract, so the number you sign is the number you pay. Single-storey builds typically run 10–14 weeks; double-storey 16–24 weeks — both confirmed at quote, not discovered mid-build.
Westfield grew as the housing district between Radstock and Midsomer Norton, its post-war estates built to house the coalfield workforce and now home to the families and commuters who make the Somer Valley their own. The stock is dominated by solid post-war semis, terraces and bungalows — well-built housing that rewards structural investment, with plot sizes that generally take a rear extension and roofs that often suit dormer loft conversions. Typical work here is whole-home refurbishment, structural extensions and the practical upgrades that bring 1950s and 1960s housing up to modern family standards, all delivered on the same fixed-quote basis as the rest of our Somer Valley coverage.
