Single and double storey extensions in Ealing. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Ealing, working with the generous plots of Edwardian villas and the tighter footprints of Victorian terraces in Acton and Southall. Drawing on 30+ years in W3, W5 and UB6, we handle foundations, steelwork, roofing and full fit-out so your extension is delivered by one team from groundworks to decoration.

The side return alongside the rear closet wing is the classic space to claim on an Ealing terrace. Infilling that narrow strip and extending to the rear turns a dark galley kitchen into a bright open-plan kitchen-diner. The work usually needs new foundations dug to a depth agreed with building control, steel beams to carry the existing rear wall, and a flat or pitched roof with rooflights to bring light deep into the plan.
On the wider Edwardian villas near Ealing Common and Walpole Park, there is often room for a more generous single or double storey extension. We match the new brickwork, reinstate cornicing and skirting where period rooms are affected, and tie the new structure into solid walls properly. Whether the plot is tight or generous, we sequence groundworks, steelwork and roof so the shell is watertight before the internal fit-out begins.
Many single storey rear and side-return extensions in Ealing fall under permitted development, but this is not guaranteed. Larger schemes, double storey work, front extensions and any property in a conservation area or that is listed will need a full planning application to Ealing Council. We assess your specific house and postcode, advise honestly on which route applies, and can arrange drawings and the application so the design is approved before we build.
Extensions are also structural, so alongside any planning approval the work must meet building regulations, with foundations, steelwork and insulation inspected and signed off. Because Ealing terraces share party walls, excavating near the boundary or building off a party wall triggers the Party Wall Act, so notices are served on your neighbours in advance. We coordinate planning, building control and party wall matters together so nothing stalls the build.
Ealing homeowners trust GS Renovation because we deliver the whole extension, foundations, steel, roof and fit-out, as one accountable project backed by 30+ years across W5, W13 and UB1. We advise honestly on permitted development versus planning, handle building control and party wall notices, and match new work to the character of your Victorian or Edwardian home.
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!
