Structural alterations, new openings and steel support in Stratford. Trusted, professional, 30+ years' hands-on experience.
From forming new openings in warehouse-conversion flats to replacing tired joists in Forest Gate's Victorian terraces, GS Renovation carries out structural alterations right across Stratford. With over 30 years of experience in E15 and the wider Newham area, we handle supported openings, replacement joists and underpinning with the engineer's calculations and building control sign-off included.

Stratford's housing stock is unusually varied, running from new-build riverside apartments near the Royal Docks to solid Victorian terraces towards Forest Gate and East Ham. Each type calls for a different approach: a supported opening in a converted warehouse deals with concrete or heavy brickwork, while an alteration in an E15 terrace works with traditional timber floors and load-bearing masonry. We assess exactly what you have before proposing anything.
Whatever the alteration, the principle stays the same. A structural engineer designs the solution, we install steel beams onto padstones where openings are formed, prop safely and demolish in stages, and strengthen or replace joists where long spans or old notching have weakened a floor. Where foundations have moved, underpinning is designed to suit the ground conditions common across Newham's low-lying, formerly marshy land near the river.
Internal structural alterations are governed by the Building Regulations rather than planning permission, so unless you are altering the exterior of a home in a conservation area or a listed building, there is no planning application to make. Newham Council's building control inspects the works and issues the completion certificate. We manage the notice and the inspection stages so nothing is missed and the paperwork is complete at the end.
In leasehold flats we also secure the freeholder's licence to alter and coordinate with the managing agent, and where an alteration touches a wall shared with a neighbour the Party Wall Act may apply. You serve any notices needed, prop and support at every stage of the work, and keep an occupied E15 home clean and workable while the alteration is carried out.
Owners across E15 trust GS Renovation with structural alterations because we bring one team and full accountability: engineer-designed beams and underpinning, party wall or freeholder consent arranged, and Newham building control sign-off handled from notice to certificate. Three decades of alterations in Stratford's converted and Victorian homes mean the detail is right, the support is safe and the site stays tidy.

FAQ
Sometimes, though rarely by as much as people fear. The structural part of structural alterations are broadly similar; what differs in a warehouse-conversion and new-build Stratford house is reinstating cornice, floors and plaster around the E15 works. Those appear as separate lines on the quotation. GS Renovation has worked on this stock for years and prices it from experience rather than caution. Ring 07472 424 226 and we will describe recent work on similar E15 properties in Newham. 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.
Most of the disruption lands in the first phase and then eases considerably. The structural stage of structural alterations at an E15 property is noisy and dusty for a defined period, after which your Stratford home comes back in stages. GS Renovation dust-seals the work area, protects floors and clears up daily. Working hours are agreed before we start anywhere in Newham. Ring 07472 424 226 and GS Renovation will explain what to expect at your E15 address.
Properly, because in a terrace it affects everyone. GS Renovation agrees working hours with a Stratford household before structural alterations begins, dust-seals the E15 work area, and leaves the site clean each evening. Waste is removed rather than allowed to accumulate. Full insurance and a named manager on the Newham site cover the rest. Ring 07472 424 226 and we will explain the site rules. Full insurance covers every E15 project we run across Newham.
The structural engineer. GS Renovation is a contractor: we appoint and coordinate the engineer, arrange the temporary works, and build to their design at your Stratford address. We do not produce calculations ourselves, and any builder claiming to is worth questioning.
They make the job more interesting rather than more difficult. What structural alterations need in Stratford is proper investigation before anything structural is touched at E15, and an engineer's design where the load path is changing. GS Renovation coordinates that as standard. Over 30 years of hands-on experience is mostly knowing where to look in Newham. Ring 07472 424 226 and we will explain how structural alterations are planned in an E15 house in Stratford.
Usually not. Internal structural alterations, new openings, replacement joists and underpinning are controlled under the Building Regulations, and Newham building control signs them off. Planning permission is only needed for exterior changes to a listed building or in a conservation area. If you live in a leasehold flat, the freeholder's licence to alter is the consent to secure first.
Yes, and at no extra cost within Newham. GS Renovation covers Stratford and the E15 area for structural alterations and much of the wider East London besides. Distance only becomes a factor well beyond East Ham, and we will say plainly if a property is too far. Email info@gsrenovationltd.co.uk with the postcode and we will book a free survey. Nothing is owed for the E15 visit either way. Small jobs and full projects are treated on the same basis.
