Corsham
Character cottage updates, historic stone masonry and high-street standard finishes — preserving Corsham's distinctive market-town identity.
- 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.
Corsham's historic High Street, overlooked by Corsham Court, and its surrounding stone cottages represent a unique concentration of Cotswold-style building stock. Our work here focuses on preserving that character — from matching the distinctive oolitic limestone to reinstating traditional lime renders and ensuring new additions sit comfortably within the existing streetscape. Every project, whether a cottage modernisation or a larger-scale conversion, receives the same meticulous material specification. High Street conservation zone compliance, Bath stone sourcing and matching, and town-centre traffic management for site logistics are all part of the standard scope.
