House Extensions Ealing

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.

Side-return and rear extensions in Ealing

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.

Planning and party walls for Ealing extensions

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.

FAQ

Frequently Asked Questions about House Extensions Ealing

What should I budget for house extensions in Ealing?

Budget for the work itself plus a sensible contingency for what a survey cannot see. On a Victorian and Edwardian terraced property near W3 the usual unknowns with house extensions sit behind plaster and under floors, so GS Renovation prices what is visible and flags the rest openly. The Ealing Council building control fee belongs in your Ealing budget too. GS Renovation would rather over-explain an Ealing figure than surprise an Ealing homeowner halfway through the work. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

How many trades are on site during house extensions in Ealing?

It varies by stage, and they are coordinated rather than overlapping. The structural phase of house extensions at a W3 property is a small team, after which electricians, plumbers, plasterers and decorators follow in sequence through your Ealing home. GS Renovation manages them in-house so nobody waits on anybody. One named project manager runs the Ealing site throughout. Ring 07472 424 226 and GS Renovation will name the trades due at a W3 property in Ealing.

What do I get from GS Renovation on a house extensions job in Ealing?

An itemised quotation, a written programme and one named project manager. For house extensions at a W3 property that also means full insurance, Ealing Council building control coordinated on your behalf, and a five year guarantee on installations. GS Renovation protects the Ealing site and clears up daily. You deal with the same people from first survey to final certificate. Ring 07472 424 226 to hear how an Ealing job runs. The Ealing certificate follows completion.

Do I need planning permission for an extension in Ealing?

Many single-storey rear extensions in Ealing fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full permission. We assess your W3 property and manage both the Ealing Council application and building control.

Can you handle house extensions in a Victorian and Edwardian terraced property in Ealing?

Comfortably. What house extensions demands in an older Ealing home is investigation first, because aged materials and irregular dimensions change both method and programme at a W3 property. GS Renovation prices that from experience rather than guarding against it. Ring 07472 424 226 and we will talk through what your Ealing house is likely to need. The W3 survey is free, and the written Ealing quotation for house extensions follows only a few days later.

Does my Ealing side-return extension need planning permission?

It depends on your property. Many single storey side-return and rear extensions in Ealing are permitted development, but conservation areas, listed buildings, larger footprints and double storey schemes usually need a full planning application to Ealing Council. Either way the work must meet building regulations. We assess your house and postcode and tell you honestly which route applies before any work begins.

Do you take on house extensions across the whole of Ealing?

We do, and the borough boundary is not something we price against. What decides whether GS Renovation takes a house extensions project is capacity and scope rather than whether the W3 property is in Ealing or elsewhere in Ealing. Quotes are free and carry no obligation. Call 07472 424 226 for current availability. Aftercare visits reach a West London address just as easily. Nothing is owed for the W3 survey or for the written quotation.
