GS Renovation designs and builds extensions across South Kensington, from rear additions to full wrap-around projects on the Georgian and Regency townhouses of the museum quarter. With over 30 years in SW7 and the Royal Borough of Kensington and Chelsea, we manage the groundworks, steel, roof and fit-out as one project.
Rear and side-return extensions in South Kensington
Many South Kensington houses have a rear closet wing and a narrow side return that, once infilled, transforms a cramped lower-ground kitchen into a generous open-plan space. We dig and lay foundations suited to the ground and the neighbouring structures, then tie the new build into the original brickwork with steel where the old rear wall is removed.
Plots in SW7 are often tight and hemmed in by neighbours on both sides, so we plan access, waste removal and material handling carefully. A steel beam sized by the engineer usually spans the new opening, and building control inspects the foundations, the structure and the finished envelope before the space is signed off.
Planning and party walls in South Kensington
Whether your extension is permitted development or needs a full planning application depends entirely on the property. Many South Kensington houses sit within a conservation area and a good number are listed, which tightens permitted development rights considerably, so a submission to the Royal Borough of Kensington and Chelsea is often required. We advise honestly on which route your SW7 house falls under before any work starts.
Because the houses are terraced and share party walls, most extension projects trigger the Party Wall etc. Act, meaning notice must be served on adjoining owners. We coordinate the planning drawings, the party wall process and the building regulations approvals so the paperwork and the programme move together rather than holding one another up.
