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.
Radstock's streets of terraced miners' cottages and Victorian housing were built for the Somerset coalfield workforce — a history the town now preserves at Radstock Museum, housed in the old Market Hall — and the town has spent the decades since reinventing itself without losing that solid, no-nonsense housing stock. Owners here want the same thing we hear across the Somer Valley: genuine build quality and honest pricing, without a Bath postcode premium attached. Former mine-shaft records are a real consideration on some sites, and we survey for them as standard before any groundwork begins. From kitchen and bathroom refurbishments to full structural renovations, we apply the same rigorous project management regardless of project size — and that honest, fixed-price refurbishment work is exactly what Radstock owners ask us for.
