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.

FAQ
Free, always. Pricing house extensions without seeing a Vauxhall house is guesswork, so the visit to SE11 is part of quoting rather than a service to bill for. GS Renovation allows enough time on site to look properly, including at the Georgian and early Victorian details that move the figure. Nothing is owed if you go elsewhere in Lambeth. Ring 07472 424 226 or email info@gsrenovationltd.co.uk and we will find a Vauxhall appointment time that suits you. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Yes, and it is issued in writing with the quotation. The house extensions programme for your SE11 property names the start date, the stages, the Lambeth Council inspection points and the completion date. If a Georgian and early Victorian building forces a change, GS Renovation tells a Vauxhall homeowner immediately and re-plans rather than quietly slipping. Ask any Lambeth builder for the same document. Ring 07472 424 226 and we will send a sample SE11 programme before you decide.
We build to a design, we do not write one. Where house extensions in an SE11 home involves beams, openings or altered load paths, GS Renovation appoints an independent structural engineer and coordinates them through Lambeth Council sign-off. That separation protects the Vauxhall homeowner. Propping and sequencing on site are then ours to get right. Ring 07472 424 226 and we will explain the Lambeth sequence. The engineer is appointed and paid through the Lambeth contract.
It can. The Community Infrastructure Levy applies above 100 square metres of new floorspace, though a residential extension to your own home usually qualifies for relief if it is claimed before work starts. Missing that claim is expensive, so we flag it early on Vauxhall projects.
Yes, constantly. A large share of the housing around SE11 is exactly that, and house extensions in it is planned around how those buildings were put together rather than adapted halfway through. GS Renovation surveys each Vauxhall property before committing to a method or a price. The same applies across Lambeth and over in Brixton. Ring 07472 424 226 and we will describe how house extensions usually runs in an SE11 house of that age in Vauxhall.
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.
Yes, Brixton is well within the patch. House extensions runs across Vauxhall, the surrounding Lambeth and the areas between them, so neither address is a stretch. GS Renovation charges nothing for the survey at an SE11 property or anywhere else nearby. Ring 07472 424 226 and we will confirm availability for both. Building control is coordinated with Lambeth Council on each of them. Small jobs at either address are quoted on exactly the same basis.
