Structural alterations, new openings and steel support in Battersea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation carries out structural alterations throughout Battersea's Victorian and Edwardian terraces, from new openings in the side return to replacement joists and underpinning near the River Thames. With more than 30 years working in SW11, we handle new openings, supported beams and foundation work as one engineered, certified project.

Battersea's bay-fronted terraces were built for smaller, cellular rooms, so most alterations involve forming new openings, replacing tired joists over the closet wing, or introducing a supported opening between the kitchen and the rear addition. Every opening in a loadbearing element is designed by a structural engineer, who specifies the steel and the padstones it bears onto so the load above is carried safely.
Older SW11 properties sometimes show movement in the original shallow Victorian foundations, particularly on the clay soils common across South West London near Wandsworth and Balham. Where an engineer diagnoses inadequate bearing, underpinning deepens the foundation in controlled sections. We work to the engineer's sequence, one bay at a time, so the structure stays stable throughout the works.
Structural alterations are notifiable under the Building Regulations, so we lodge the work with building control and arrange inspections at each key stage, from foundation and steel installation through to completion. This is separate from planning permission, which only applies to external works in a conservation area or on a listed building rather than to the internal and foundation work itself.
Where new steels, openings or underpinning affect the wall shared with the neighbouring house, the Party Wall Act applies and notice is served before excavation or cutting begins. We coordinate the engineer and Wandsworth Council's building control together, so nothing falls between trades and you finish with a fully signed-off, structurally sound result.
Homeowners across SW11 choose GS Renovation because structural alterations are handled by one team from engineer's design to building control certificate. We manage the steel, the padstones, the propping, any underpinning, and the working tidily in an occupied Battersea home and backed by more than 30 years across Wandsworth.

FAQ
The method is deliberately dull: measure, scope, itemise. Nothing about structural alterations are quoted over the phone for a Battersea home, because a blind figure is a figure that changes later. We look at the SW11 property, allow for its Victorian and Edwardian terraced construction, and issue a written quotation. GS Renovation works that way throughout Wandsworth and it is why the figures hold. Email info@gsrenovationltd.co.uk with the SW11 address and we will arrange a free survey. 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.
The written programme is part of the quotation for every Battersea home. It covers the structural alterations stages, the trades in sequence, and the points at which Wandsworth Council must inspect before work is concealed at SW11. GS Renovation books those inspections ahead so the job is not waiting on paperwork. Ask on 07472 424 226 about current start availability across Wandsworth. Nothing is concealed at an SW11 address before Wandsworth Council has been to see it.
One accountable team, full insurance, and no surprises on the invoice. GS Renovation carries out structural alterations at your SW11 address with its own people, agrees any variation in writing first, and hands over the Wandsworth Council completion certificate at the end. That document matters when a Battersea property is sold. Free quotes and no obligation apply across Wandsworth. Email info@gsrenovationltd.co.uk and we will arrange a visit. The Wandsworth certificate is yours at completion.
Yes, building regulations approval and an engineer's design, and it is notifiable under the Party Wall Act where it falls within three metres of a neighbouring structure. Underpinning at an SW11 address is carried out in controlled bays to keep the existing building stable throughout.
Investigation first, method second, price third. Assuming how a Victorian and Edwardian terraced Battersea house is built is the commonest mistake on structural alterations, so GS Renovation opens up carefully at SW11 rather than relying on drawings. The sequence then protects the rest of the building. Weekly updates keep you ahead of what we find in Wandsworth. Ring 07472 424 226 and we will describe what structural alterations have recently found in comparable SW11 properties right across Wandsworth.
Not necessarily. Cracking can have several causes, so we start with a structural engineer's assessment before recommending anything. If the original shallow Victorian foundations on SW11's clay soils are found to be inadequate, underpinning deepens them in controlled sections. If the cause is something else, we address that instead rather than carrying out unnecessary foundation work.
Never for a Battersea address. Charging for travel would make the structural alterations figure depend on where our van started rather than on your SW11 property, which is not how GS Renovation prices anything. Distance only matters well beyond Putney, and we would say so upfront. Call 07472 424 226 for a no-obligation quotation. The survey across Wandsworth is free in every case. Two similar homes across Wandsworth would receive comparable figures either way.
