GS Renovation designs and builds extensions across Richmond upon Thames, from riverside homes near the Thames to period cottages in Barnes and Teddington. With over 30 years working on the borough's Georgian, Victorian and listed stock, we handle groundworks, steel, roofing and fit-out, guiding you through permitted development or a full planning application to Richmond Council.
Rear and side-return extensions in Richmond
The side-return extension is a favourite in Richmond's Victorian terraces, infilling the narrow alley beside the rear closet wing to widen a cramped kitchen into an open-plan kitchen-diner. We dig and pour foundations to suit the ground and any nearby trees, then install a steel frame where original walls come out. A glazed roof or rooflights bring light deep into a plan that period houses often leave dark at the centre.
Rear extensions suit the larger plots found around Kew and TW10, adding a full-width room across the back of the house. Wrap-around designs combine both, though on tighter Twickenham plots we plan carefully around boundaries and party walls. Whether the project falls under permitted development or needs planning permission depends on size, height and whether the property is listed or in a conservation area, which is common across this borough.
Planning and party walls in Richmond
Not every Richmond upon Thames extension needs planning permission. Many single-storey rear extensions fall within permitted development rights, but those rights are removed or restricted for listed buildings and in conservation areas, both of which are widespread across TW1, TW9 and TW10. We assess your property early and, where required, prepare and submit a full application to Richmond Council, managing the drawings and the process so you know where you stand before we build.
Because the borough's terraces and semis share boundaries, extensions frequently trigger the Party Wall Act. Excavating near a neighbour's foundation or building up to the line means serving notice before work starts. Alongside planning, the build itself needs building regulations approval covering foundations, insulation, structure and drainage, all inspected by building control. We fold these approvals into one programme so the groundworks, steel and roof progress without stalling on consents.
