What Weybridge Homeowners Say About Our House Extension Specialists
Side-return infill extension on our 1970s detached in Weybridge. Two-storey gain - utility on the ground, en-suite bedroom on the first. Cavity-tray detail done properly. Total project £88840 across 15 weeks. FMB-credentialed builder, structural calcs done in-house.
Compared four extension builders through BestBuilders for the Weybridge job. Two FMB-affiliated builders, two not. Went with the one whose references checked out best. Foreman walked the spec sheet through with us before any digger arrived. Quote was £100060, invoice came in £195 lower. Moved out for two weeks during the demolition and steel install, the rest was bearable.
Three years on, EPC went from D to B thanks to the spec they used. Builder we found via BestBuilders in Weybridge designed-in concealed downlights so the ceiling has no visible fittings. Total £79620. Decided to stay rather than move - the extension solved the space problem entirely.
