Structural alterations, new openings and steel support in Dalston. Trusted, professional, 30+ years' hands-on experience.
From new openings to replacement joists and underpinning, GS Renovation carries out structural alterations across Dalston's E8 streets. Our 30+ years working on bay-fronted Victorian and Edwardian terraces with rear closet wings means we understand how these houses are built, and how to alter them without compromising the structure above.

The closet wings and side returns on Dalston terraces make them ideal for reconfiguring, but every new opening changes how loads travel down to the foundations. Whether you want a supported opening between the kitchen and a side-return extension, or a wider doorway through a structural wall, a structural engineer designs the beam, the padstones and the bearings so the alteration is proven on paper before we build it.
Older E8 houses often need more than a single beam. Decades of use leave floor joists sagging, notched or affected by damp near the closet wing, so replacement joists frequently form part of the same job. Where movement or a poor original footing is a factor, underpinning may be recommended to stabilise a wall before new openings are formed. We sequence the work so the house stays supported throughout.
Internal structural alterations are controlled under the Building Regulations, so Hackney Council's building control approves and inspects the work rather than the planning department. Planning permission only comes into play for exterior changes in a conservation area or to a listed building. We make this distinction clear from the outset so you know exactly which consents your project actually needs.
Because so many alterations involve a shared party wall or its foundations, especially underpinning near the boundary, the Party Wall Act usually applies and you serve notice on the neighbour before work begins. We coordinate the engineer, the temporary support and the building control inspections, and provide the completion certificate you will want when you come to sell your E8 home.
Homeowners across Dalston trust GS Renovation with structural alterations because we cover the full scope under one roof: engineer-designed openings, replacement joists, underpinning where needed and building control sign-off. Three decades on Hackney's terraces mean we anticipate the quirks of these houses, work cleanly around your daily life and certify everything properly.

FAQ
Only a survey answers that honestly. Two Dalston houses of the same size can differ once structural alterations are scoped, so we look at the E8 property first, then price the structure, the trades and the Hackney Council approvals as separate lines you can compare. That written quotation is what GS Renovation stands behind across Hackney and Shoreditch. Nothing is owed for the E8 survey if you decide against going ahead with structural alterations in Dalston. 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.
Structure first, then services, then finishes, with the Hackney Council inspections fixed between them. That sequence is what stops trades undoing each other on a structural alterations job at an E8 address, and it is written into the programme GS Renovation issues with the quotation. Your Dalston project is updated against it weekly. Nothing is concealed anywhere in Hackney before it has been inspected. Ask GS Renovation on 07472 424 226 for the written E8 programme before you commit.
It helps, provided the firm is genuinely local rather than badged that way. Knowing how Edwardian bay-fronted houses with generous ceiling heights and long rear gardens are built means structural alterations at an E8 address is priced from experience instead of caution, and a team already working in Hackney can reach your Dalston property quickly. GS Renovation is on sites nearby most weeks. Check insurance and reviews whoever you choose. Ring 07472 424 226 and ask where we are currently working. Insurance and Hackney references are available beforehand.
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 Dalston address. We do not produce calculations ourselves, and any builder claiming to is worth questioning.
We do, week in and week out. Edwardian bay-fronted houses with generous ceiling heights and long rear gardens make up much of Dalston, so structural alterations on them is core work for GS Renovation rather than an occasional job. The E8 survey establishes what is actually there before anything structural is touched. Hackney Council building control is coordinated by us in the usual way. Ask on 07472 424 226 what an E8 property of that age typically needs before structural alterations can even begin in Dalston.
Internal structural alterations such as new openings, replacement joists or underpinning are covered by the Building Regulations and signed off by Hackney building control, not planning. You would only need planning permission for exterior changes within a conservation area or to a listed building. We confirm exactly which approvals your E8 project requires before any work starts.
We take those enquiries regularly. A property sitting just outside Dalston is often closer to a current Hackney site than one at E8, so structural alterations there is sometimes easier rather than harder. GS Renovation charges nothing for the survey. Call 07472 424 226 and we will check the next available slot. Building control is coordinated with Hackney Council wherever the address sits. Nothing at all is owed for the E8 visit or the written quotation.
