Single and double storey extensions in Battersea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Battersea, working with the bay-fronted Victorian and Edwardian terraces that define SW11. From side-return infills near Clapham Common to rear extensions backing onto quiet streets by Battersea Park, our 30+ years of local building means foundations, steelwork, roofing and fit-out are handled by one accountable team.

The classic Battersea extension fills in the side return, that narrow strip of ground alongside the rear closet wing, to widen a cramped galley kitchen into a bright open-plan space. Because the return sits tight against the boundary, we underpin or form new foundations carefully, install steel beams to carry the existing rear wall, and often add a glazed roof to pull light deep into the plan.
These terraces sit close to their neighbours, so the Party Wall Act almost always applies where we build off or near a shared wall. We serve the notices, protect the adjoining property and sequence the groundworks to keep disruption down. The result opens up the ground floor of a period SW11 house without losing the proportions and features that make these homes worth extending.
Some extensions in Battersea fall under permitted development, meaning you can build within set size and height limits without a full planning application. Others need planning permission from Wandsworth Council, particularly larger rear or wrap-around builds, anything affecting the front elevation, or homes within a conservation area or with an article 4 direction. We assess your specific house before committing to a route.
Whichever path applies, the structural and building regulations side is separate and always required. Foundations, steel beams, drainage, insulation and fire safety are all inspected by building control. We advise honestly on whether your Battersea project is likely to be permitted development or need an application, help with drawings, and build to the approved design so the finished extension passes inspection and adds lasting value.
Homeowners across Battersea choose GS Renovation because we take an extension from first sketch to final coat with one team. We know the side returns, closet wings and party walls of SW11 terraces, we handle council and building control, and our 30+ years mean the groundworks and steelwork are done right the first time.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!

Yes. A large share of Battersea's homes are Victorian and Edwardian terraced properties, and we renovate them regularly.
