GS Renovation designs and builds extensions throughout Hammersmith, tailored to the bay-fronted Victorian and Edwardian terraces that fill the W6 streets between the River Thames and Westfield London. Drawing on more than 30 years of building experience, we handle foundations, steelwork, roofing and full fit-out to add usable space to these period terraced homes.
Side-return and rear extensions in Hammersmith
The classic Hammersmith project fills in the side return alongside the rear closet wing, widening a narrow galley kitchen into a bright open-plan space that runs the full width of the house. On tighter W6 plots we often combine the side return with a modest rear extension, then knock through into the middle reception room with a steel beam to create a single kitchen-diner opening onto the garden.
We start with proper foundations and groundworks, allowing for the shallow footings and drain runs common on these older terraces, then build the walls, install the steel and form the roof. Rooflights and glazed rear doors bring light deep into the plan, which matters in period houses where the middle of the terrace can otherwise feel dark.
Planning and party walls in Hammersmith and Fulham
Some extensions in W6 fall under permitted development, but many do not, so the route depends on your specific property. If your home sits in a conservation area, has been previously extended, or you want a larger footprint, you will usually need a full planning application to Hammersmith and Fulham Council rather than relying on permitted development rights.
Either way, the structural work is covered by building regulations and inspected by building control, which is separate from planning. Because these terraces share party walls with both neighbours, most extensions also trigger Party Wall Act notices for excavation near the boundary or for cutting into the shared wall. We guide you through all three strands so the project starts on solid legal footing.
- Full fit-out, finishing and making good
- Planning applications and permitted development assessments
- Brickwork and mortar matched to the existing elevation
- Single and double storey extensions
