Single and double storey extensions in Vauxhall. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Vauxhall, working with the Georgian and Regency townhouses and the newer riverside developments that define SE11. With over 30 years in South London, we handle foundations, steelwork, roofing and full fit-out, and we guide you through whether your project is permitted development or needs a planning application to Lambeth Council.

The most common Vauxhall extension opens up the back of a period townhouse, either a rear extension into the garden or a side-return infill that captures the wasted alley beside the closet wing. We dig and pour foundations to suit the ground and any nearby trees, build in blockwork or brick to match, and drop in the steel beams that let the new space flow into the existing kitchen and reception rooms.
Double-storey and wrap-around extensions are possible on the larger plots towards Kennington, adding a bedroom or en-suite above a widened ground floor. Every layer, from the damp-proofing and insulation to the roof and rainwater goods, is built to current building regulations. Because so many SE11 homes are terraced, we also manage the party wall agreements with both neighbours, keeping relations calm while the excavation and steelwork go in next to their properties.
Whether your Vauxhall extension is permitted development or needs full planning permission depends on the property. Many single-storey rear extensions fall under permitted development rights, but those rights are removed or reduced on listed buildings and within conservation areas, both common in this part of Lambeth. We assess your home early, advise honestly on the route, and prepare or coordinate the planning application to Lambeth Council where one is required.
The riverside flats bring their own rules. Leaseholders generally cannot extend outward, so we focus instead on internal reconfiguration under the freeholder's licence to alter and the managing agent's consent. Whichever building you own, the structural side is a building regulations matter signed off by building control, separate from planning. We keep the two processes clear and moving so your extension is designed, consented and built without confusion or costly surprises.
Homeowners across Vauxhall choose GS Renovation because we build the whole extension, from the first trench to the final coat of paint, as one accountable job. We know the SE11 housing stock, the conservation constraints and Lambeth's planning route, and we handle the party wall and building control side too. With 30+ years behind us, the programme stays on track and on budget.
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!

Many single-storey rear extensions in Vauxhall fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full planning permission. We assess your property and manage both the planning application and building control.
Yes. A large share of Vauxhall's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
It depends on your property. Many single-storey rear extensions in Vauxhall are permitted development, but if your home is listed or sits within a Lambeth conservation area, which is common here, those rights are often restricted and a planning application is needed. We assess the house first, tell you honestly which route applies, and manage the submission to Lambeth Council where required.
