GS Renovation designs and builds extensions across Kennington, adding space to the Georgian, Regency and Victorian homes of SE11 without spoiling their character. With more than 30 years working across Lambeth, near Vauxhall, Brixton and the South Bank, we handle foundations, steelwork, roofing and the full fit-out as one accountable project.
Rear and side-return extensions in Kennington
The most popular extension on a Kennington terrace is the rear or side-return infill, filling the narrow strip beside the original closet wing to widen a cramped kitchen into an open-plan kitchen-diner. These period plots can be tight, so we design foundations that respect the neighbours' walls and existing drainage, then form the opening with an engineer-designed steel beam signed off by Lambeth building control. Glazed roofs and rooflights pull daylight deep into the plan.
A double-storey rear extension can add a bedroom or bathroom above the new ground-floor space, which changes the loading and calls for heavier foundations and steel. We match brickwork and detailing to the existing Georgian or Victorian elevation so the addition sits comfortably. Throughout, we protect the retained house, manage the muck-away within these SE11 streets and keep the property secure and weathertight while the shell goes up.
Planning and party walls around SE11
Whether your Kennington extension is permitted development or needs a full planning application depends entirely on the property. Many modest rear extensions fall under permitted development, but that right is often removed or restricted where the home is listed or within one of Lambeth's conservation areas, which covers a large part of Kennington. In those cases a full application to Lambeth Council is required, and we help prepare and submit the drawings and supporting information.
Extensions almost always trigger party wall matters, because you build up to or along the boundary shared with the adjoining owner and excavate near their foundations. The Party Wall Act then requires formal notice, and we coordinate with your surveyor so awards are agreed before groundworks begin. Separately, the structure itself is signed off under building regulations by Lambeth building control, which is a different process from the planning decision.
