GS Renovation designs and builds extensions throughout Hammersmith and Fulham, adding space to bay-fronted Victorian and Edwardian terraces in W6, W12, W14 and SW6. With more than 30 years in West London, we handle single and double storey, rear, side-return and wrap-around extensions from foundations to final fit-out.
Side-return extensions across Hammersmith and Fulham
The classic project on the borough's terraces is the side-return extension, filling the narrow strip of dead ground beside the rear closet wing to widen a cramped galley kitchen into a bright, open-plan kitchen-diner. Off the streets around Parsons Green and Fulham, this transforms how a Victorian house lives, and we often combine it with a rear extension to create a full wrap-around footprint opening onto the garden.
We dig and pour the foundations, build the walls, install the steel beams that carry the old rear wall, and form a roof with rooflights or a glazed lantern to pull daylight deep into the plan. Groundworks near the Thames in SW6 can meet higher water tables, so we adapt the foundation design to the ground conditions we find on site.
Planning and party walls in Hammersmith and Fulham
Many rear and side-return extensions on these terraces fall under permitted development, but not all do. Corner plots, flats, homes in a conservation area and anything beyond the permitted size limits need a full planning application to Hammersmith and Fulham Council. We assess your property early and tell you clearly which route applies, then prepare drawings and manage the submission so you are not left guessing.
Whichever planning route you take, the structural work is signed off separately under building regulations by building control. Because you are extending against a shared boundary to neighbours are almost always needed on these closely spaced streets. We coordinate planning, party wall matters, building control and the full fit-out, including kitchen, bathroom, electrics and decoration, as one managed project.
