We design, plan and build house extensions across East Sheen and the wider Richmond upon Thames borough — one team, one fixed price, one project manager from sketch to handover.
Conservation areas, Article 4 directions, party-wall hotspots — every Richmond upon Thames street has its own permission map. We have submitted dozens of approved schemes across East Sheen and the surrounding postcodes.
No subcontractor juggling. From the first sketch through structural engineering to final snagging, your project moves through people who all sit in the same office and answer to the same project manager.
You pay in stages, only after each stage is signed off. Variations only happen when scope genuinely changes — and they go through written authorisation, never a verbal "while we are at it".
