- 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.
Lansdown is Bath at its most architecturally distinguished — sweeping Regency terraces like Lansdown Crescent, the eccentric silhouette of Beckford's Tower on the hill above, substantial Georgian villas, and some of the city's finest period interiors. Work here is never routine. Every project demands rigorous attention to period detail: correctly specified lime renders and mortars, accurate sash window restoration or replacement, period-appropriate internal finishes, and the kind of project management that protects premium properties throughout the build process. Our team is experienced in the Listed Building consent process and conservation officer liaison that many Lansdown properties require before works can proceed.
