GS Renovation designs and builds extensions throughout Hanwell, tailored to the bay-fronted Victorian and Edwardian terraces that line its streets near the river. With more than 30 years working across Ealing and W7, we handle groundworks, steel, roofing and full fit-out, giving these period homes the extra ground floor space families here want.
Side-return and rear extensions in Hanwell
The side return, that narrow strip of ground running alongside the rear closet wing, is the classic Hanwell extension. Filling it in widens a cramped galley kitchen into a proper open-plan kitchen-diner, usually with a steel beam replacing the old external wall and rooflights bringing daylight deep into the plan. A rear extension pushes further into the garden, and a wrap-around combines both for the biggest transformation.
We start with the groundworks, which in Hanwell means checking for nearby trees and drainage runs and digging foundations to the depth building control requires. Then come the steel, the walls, the roof and the fit-out. Because we run the whole build with one team, the structure, the services and the finishes all come together without the gaps that happen when trades are hired piecemeal.
Planning and permitted development in Ealing
Whether your Hanwell extension needs a full planning application or falls under permitted development depends on the property. Many single-storey rear extensions on unaltered terraces proceed under permitted development within the size and height limits, while double-storey work, anything on a flat facing the highway, or a home in a conservation area usually needs a planning application to Ealing Council. We assess your specific house before drawing anything.
Separately from planning, every extension must meet building regulations, which govern the foundations, the steel, insulation, fire safety and drainage, and building control inspects these as the work proceeds. Where your extension touches a wall shared with a neighbouring terrace, the Party Wall Act applies too. We coordinate all three strands, planning, building control and party wall, so nothing stalls the build.
