Structural alterations, new openings and steel support in Acton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation carries out structural alterations throughout Acton, from new openings in bay-fronted terraces to replacement joists and supported openings in the rear closet wings. With more than 30 years working on West London's Victorian and Edwardian housing, we handle underpinning, new steel and made-good structures across the W3 postcode with full certification.

Acton's terraces come with the quirks of their age: bouncy floors on undersized original joists, cracked lintels over bay windows, and rear closet wings that owners want opened into the main house. Each of these is a structural alteration in its own right. We start with an engineer's assessment so the fix, whether new joists, a replacement lintel or a fresh supported opening, is designed for the real loads rather than assumed.
New openings between the closet wing and the kitchen, or through into a side return, are formed with a correctly sized steel beam bearing onto padstones. Where old foundations have settled, underpinning may be needed to stabilise the wall before anything else proceeds. We prop, cut and build in sequence, checking the structure above at every stage so the alteration is sound long after we have left the W3 street it sits on.
Because so much of Acton's structure is shared, many alterations touch the party wall dividing you from the neighbour. Cutting a new opening into it, bearing steel onto it or underpinning alongside it all fall under the Party Wall Act, so you serve the relevant notices before work starts. Handling this early keeps the neighbour informed and stops a dispute from holding up your project once the props are in.
Structural alterations inside the home are a Building Regulations matter for Ealing Council's building control, not a planning application, so long as you are not altering a conservation-area or listed exterior. The engineer's calculations are submitted, an inspector signs off the beam, underpinning or new joists at each stage, and you receive the completion certificate. We coordinate the engineer and the inspections so you deal with one team throughout.
Homeowners across Acton trust GS Renovation because structural alterations are exactly what we do: engineer-designed openings, joists and underpinning served, and Ealing building control sign-off all managed under one roof. We work tidily in occupied W3 homes, prop and stage every job safely, and stand behind the certified result with 30+ years of West London experience.

FAQ
Variation almost always comes from what has been left out. GS Renovation prices structural alterations after a survey at the W3 property, covering structure, trades, approvals and reinstatement, so the total looks higher than a quote covering half of it. An Acton homeowner comparing like with like usually finds the gap narrows. That is worth doing before anyone starts work in Ealing. Ring 07472 424 226 and GS Renovation will go through the W3 quotation with you line by line. As a rough guide, structural alterations in London ranges from roughly £1,500 for a simple opening to £15,000 or more where underpinning or major works are involved (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.
In most cases you can, and we plan the Acton works around it. The question is whether structural alterations take out the kitchen, the bathroom or the heating at your W3 property for any length of time, and the programme shows exactly when. GS Renovation phases the Ealing job room by room where staying put matters. Sometimes moving out for one week is simply easier. Ring 07472 424 226 and GS Renovation will describe how a W3 household in Acton usually manages.
Dust sheeting, sealed work areas and a clear-up at the end of every day. That is standard on a structural alterations project at a W3 property, not an extra billed to an Acton client, and it is what makes staying in the house workable. GS Renovation is fully insured and keeps access routes protected. Skips and deliveries are arranged to suit the street across Ealing. Ring 07472 424 226 and GS Renovation will explain the W3 protection used in Acton.
Only work changing the outside. Internal beams, new openings and floor structures in an Acton house engage building regulations rather than planning. A new external opening, or anything on a listed or conservation-area property, needs an application to Ealing Council.
The large majority of it. Two and three-bedroom Victorian terraces, a good many now split into flats make up most of the housing around W3, so structural alterations on them is what GS Renovation does week in and week out rather than occasionally. That familiarity is why an Acton quotation is priced from experience. References across Ealing are available on request. Email info@gsrenovationltd.co.uk and we will send addresses of several recent structural alterations projects on properties of that age near W3 in Acton itself.
Yes. Where a Victorian terrace wall in W3 has settled or cracked, an engineer assesses the foundation and specifies underpinning to stabilise it before further alteration. Because the wall is usually shared with the neighbour, the work is notifiable under the Party Wall Act, and the underpinning is signed off by Ealing building control. We manage the design and the inspections.
We are on sites across Acton and Ealing most weeks, so yes. That proximity affects three practical things on a structural alterations project: how fast the W3 survey happens, how well we know the Ealing Council process, and how quickly anyone returns afterwards. GS Renovation would rather be judged on those than on a postcode in an advert. Ring 07472 424 226 to check. References are available beforehand. The W3 survey costs nothing and commits you to nothing.
