GS Renovation designs and builds house extensions throughout Wandsworth, working with the Victorian terraces, red-brick mansion blocks and riverside homes that define the borough. With over 30 years across SW11, SW15 and SW18, we take rear, side-return and wrap-around projects from foundations and steelwork through to a finished, decorated space.
Side-return and rear extensions in Wandsworth
The classic Wandsworth extension fills the side return of a period house in SW12 or SW17, widening a narrow kitchen into a bright, open-plan room that runs out towards the garden. We dig and pour the foundations, build the new walls, install the steel beams that carry the original rear wall, and construct the roof, often with rooflights or a flat lantern to pull daylight deep into the plan.
Because these plots sit tight against neighbours, party wall matters are almost always in play. Excavating close to a boundary or building off a shared wall means serving notice under the Party Wall Act, and we help you appoint a surveyor early so the schedule stays on track. We then handle the full fit-out, from screed and underfloor heating to plaster, flooring and decoration, so you move straight into a finished room.
Planning and permitted development in Wandsworth
Whether your extension is permitted development or needs a full planning application depends entirely on the property. A modest single-storey rear extension on a Victorian terrace in SW18 may fall within permitted development rights, while a double-storey, wrap-around or riverside scheme, or any home in a conservation area, will usually need permission from Wandsworth Council. We assess your title, your position and any Article 4 restrictions before drawing anything up.
Whichever route applies, the structure itself is controlled under building regulations, so foundations, steel, drainage and insulation are all inspected and signed off by building control. We manage the drawings, the council submission where one is required, and the party wall process together, so you have a single team accountable from the first survey to the final building control certificate.
