GS Renovation designs and builds extensions throughout Fulham, working with the bay-fronted Victorian and Edwardian terraces that fill SW6. With over 30 years across the borough, we handle everything from a side-return infill near Parsons Green to a full wrap-around near Bishops Park, managing foundations, steel, roof and fit-out under one roof.
Side-return and rear extensions in Fulham
The most requested Fulham extension is the side-return infill, filling the narrow alley beside the rear closet wing to widen a cramped galley kitchen into a bright kitchen-diner. On wider plots we add a full-width rear extension, and on some SW6 corner and end-of-terrace houses a wrap-around that combines both. Each needs new foundations, steel beams over the openings and a carefully detailed roof, often with rooflights to bring daylight deep into the plan.
We start with the groundworks and foundations, checking for drains and the shared boundary before we dig, then build up in brick or blockwork to match the existing house. The old rear wall usually comes out on a steel, tying the new space to the original reception rooms. We finish with insulation, glazing, plastering and the full internal fit-out so the extension is ready to use.
Planning and party walls in Hammersmith and Fulham
Whether your Fulham extension is permitted development or needs a full planning application depends on the property. Many single-storey rear extensions fall under permitted development, but if your home has been extended before, sits in a conservation area or you want a larger or double-storey build, you will need permission from Hammersmith and Fulham Council. We assess your specific house before design so you know which route applies.
Separate from planning, every extension must meet building regulations, and building control inspects the foundations, steel, insulation and drainage as the work proceeds. Because SW6 terraces share boundaries, extensions along or near the party wall trigger Party Wall Act notices to neighbours. We coordinate the planning route, the building control inspections and the party wall process so nothing stalls the programme.
