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.
Bathwick — taking in Great Pulteney Street, the Holburne Museum setting and the elegant terraces running east from Pulteney Bridge — sits firmly within Bath's World Heritage Site, and the planning environment here is exacting, and rightly so. Our experience working within this designation means we understand what consent is required, how to specify materials and methods that will satisfy conservation officers, and how to deliver internal modernisation — updated kitchens, bathrooms and living spaces — without compromising the period envelope that makes these properties so desirable. Bathwick estate lease considerations and conservation officer pre-application engagement are managed as part of our standard project scope, so owners know where they stand before work begins.
