Single and double storey extensions in Shepherd's Bush. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds house extensions throughout Shepherd's Bush, adding space to the bay-fronted Victorian and Edwardian terraces that fill W12. With more than 30 years across Hammersmith and Fulham, we handle everything from a side-return infill to a full double storey, managing foundations, steel, roofing and fit-out under one roof.

The side return, that narrow strip of outdoor space beside the rear closet wing, is the classic place to extend a Shepherd's Bush terrace. Filling it in widens a cramped galley kitchen into a proper open-plan kitchen-diner running the full breadth of the house. The work involves new foundations tight against the boundary, a steel frame to carry the existing wall, and a roof that often includes a glazed lantern to bring light deep into the plan.
Because you are building on or near the boundary, side-return work in W12 almost always engages the Party Wall Act, so we serve notice on the neighbours before we dig. Many single-storey rear and side-return extensions fall under permitted development, but not all do, and terraces in a conservation area or with earlier extensions may need a full planning application to Hammersmith and Fulham Council. We check your property's status before design, so there are no surprises.
Where a family needs more than a wider kitchen, a double storey rear extension adds a larger kitchen-diner below and a bedroom or en-suite above. On a Shepherd's Bush terrace this means matching the new brickwork and window proportions to the Victorian original, extending the closet wing, and building foundations deep enough for the added load. A double storey addition is more likely to need planning permission than a modest single storey rear, so we assess feasibility early.
Whichever route your extension takes, building regulations always apply, covering the structure, insulation, drainage and fire safety, with building control inspecting at each stage. Our team runs the whole programme, from groundworks and steel through to plastering, the new kitchen or bathroom and final decoration. We keep the rest of your W12 home liveable while we work, protecting floors and controlling dust, and we tie the drainage into the existing runs that serve these older terraces.
Homeowners across Shepherd's Bush choose GS Renovation because we deliver the extension as a single, accountable project rather than a chain of separate trades. Thirty years of building in Hammersmith and Fulham means we know how W12 terraces behave, what the council expects and how to handle party wall matters. From engineer's drawings to the last coat of paint, one team keeps the job on programme and on budget.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!

Many single-storey rear extensions in Shepherd's Bush fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full planning permission. We assess your property and manage both the planning application and building control.
Yes. A large share of Shepherd's Bush's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
It depends on your specific property. Many single storey rear and side-return extensions in W12 fall within permitted development rights, but a larger or double storey scheme, a home in a conservation area, or a terrace that has already been extended may require a full planning application to Hammersmith and Fulham Council.
