Your trusted, local experts delivering quality workmanship and lasting protection for your home across Winsford and the wider Cheshire West region.
Single-storey rear extensions (kitchen-diners, garden rooms), single-storey side returns (often combined with a rear to make a wrap-around), double-storey side or rear (kitchen plus bedroom and bathroom above), wrap-around L-shaped extensions, garage conversions (room over garage or convert existing garage to habitable space). Every build is delivered turnkey: groundworks and foundations, drainage, blockwork and brickwork, structural steels (RSJs to current Building Regs), 1st fix joinery, plumbing and electrics, roof structure and tiling, plastering and 2nd fix joinery, kitchen install where required, finals and decoration.
Most single-storey rear extensions in Cheshire West fit Permitted Development (no full planning application required) provided depth is under 4m on a detached or 3m on a semi-detached or terraced, height is under 4m to ridge, and side extensions stay below half the width of the original house. We assess fit-for-PD on the survey and lodge a Lawful Development Certificate with Cheshire West and Chester Council where required. Conservation areas and Article 4 directions (parts of Chester city centre, Knutsford, Tarporley) restrict PD and require full planning, which we handle end-to-end with the architect.
Survey and quote (1 week), drawings and structural calculations (2 to 4 weeks), planning or PD certificate where needed (8 to 12 weeks for full planning, 4 to 6 weeks for LDC), Building Regs application (2 to 4 weeks), then on-site: groundworks and foundations (2 weeks), structure to weather-tight (3 to 6 weeks depending on size), 1st fix and roofing (2 weeks), plastering and 2nd fix (3 weeks), final fit-out and decoration (2 weeks). A typical single-storey rear runs 10 to 14 weeks on site. Double-storey 14 to 20 weeks. We give a written programme at quote and a weekly written update during the build.
Fixed-price contract before any work starts, with a clear payment schedule tied to milestones (deposit on contract, payment on slab completion, payment on weather-tight, payment on plastering complete, balance on snagging signoff). 25-year structural workmanship warranty, 10-year warranty on the fit-out, full Building Regs sign-off and completion certificate handed over. Public liability insurance and certificate sent with the quote. Variations during the build only added if you sign them off in writing. Call 01244 727509 or use the form below to book a survey.
