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.
Building at the back of a townhouse
A rear extension in South Kensington is built in a garden that can usually only be reached through the house, and that single fact shapes the entire job. Excavated spoil, concrete, blockwork, steel and glass all have to travel along a protected route through finished rooms, or be lifted over. Where a neighbour is willing to allow it, access through their side is sometimes quicker and we will always ask the question. Scaffold is the other early decision, because where it stands governs which route stays open for materials throughout the build.
Concrete is the hardest item to manage. A ready mixed load cannot be barrowed far, so we plan either for a pump or for mixing on site depending on what the street will take. Waste is bagged and lifted where there is no frontage to stand a skip on. All of this is settled before a start date is offered, because in SW7 the access strategy often decides the programme more than the building work does.
