Single and double storey extensions in Dalston. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions across Dalston, adding space to the Victorian and Edwardian terraces of E8 without losing their character. Drawing on more than 30 years in Hackney, we handle the groundworks, the steelwork and the fit-out, and guide you through whether your project is permitted development or needs a full application to Hackney Council.

The classic Dalston extension fills in the side return, the narrow strip beside the rear closet wing, to widen a cramped kitchen into a proper kitchen-diner. A wrap-around adds the rear as well, pushing out into the garden. Both need new foundations sensitive to the neighbouring terrace, steel beams over the openings, and a roof that ties cleanly into the original bay-fronted house.
Whether your project falls under permitted development or needs planning permission depends on the property, its size and any past extensions, and conservation controls vary across E8. We assess this honestly before you commit. Because the new walls sit hard against your neighbours are almost always required, and you serve them early so the excavation and build run to schedule.
Where the plot and the neighbours allow, a double-storey extension adds a bedroom or bathroom above the new ground-floor space, and many Dalston terraces also suit a loft conversion into the roof. These bigger projects change the roofline and are more likely to need a full planning application to Hackney Council rather than qualifying as permitted development, so early advice saves time and money.
Every extension here goes through building control for its foundations, structure, insulation, drainage and fire safety, which is separate from planning. We manage both tracks together, then complete the full fit-out, the kitchen, bathroom, electrics, plumbing, plastering and decoration, so you deal with one team from the first trench to the finished, decorated room.
Dalston homeowners choose GS Renovation because we build the whole extension, from foundations to final coat, as one accountable project. We are honest about whether you need planning permission or can build under permitted development, we coordinate the work around the party wall award your terrace requires, and we manage Hackney building control throughout. 30+ years in E8 means fewer surprises and a build that lasts.

FAQ
Not a real one, no. We can explain on 07472 424 226 how house extensions are usually approached in a Dalston home and what tends to move the cost, but the E8 property has to be seen before GS Renovation commits anything to paper. Builders who quote blind across Hackney are the ones who revise later. Email info@gsrenovationltd.co.uk with the address and we will arrange a time. The E8 survey carries no obligation of any kind. 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.
Three things, in practice: inspections, materials and late changes. A house extensions project in a Dalston home stalls when Hackney Council cannot attend before work is concealed, when a specified item has a long lead time, or when the specification changes after the E8 order is placed. GS Renovation manages the first two and warns you about the third. Nothing about a Hackney delay is hidden. The Dalston programme names when each Hackney decision is needed.
Yes, fully insured, and we will show you the certificate before work starts. GS Renovation carries cover for every house extensions project, whether the property is in Dalston or over in Shoreditch, and we are GS Renovation Ltd, company number 14611254. You can check that independently. Ask any contractor quoting for your E8 home to evidence the same. Email info@gsrenovationltd.co.uk and we will send ours for Hackney work. The certificate is offered before any E8 work starts.
Usually, if you are excavating near a neighbour's foundations or building on the line of junction, both common on Dalston plots. Notice is served before work starts and a schedule of condition protects both parties. We prepare the paperwork for your E8 address.
Yes, mainly in the preparation and the making good rather than the structural work itself. House extensions at an E8 property of that age means confirming the load path before design, then reinstating plaster, floors and joinery to match. GS Renovation programmes both into the Dalston job. The structural stage is broadly comparable to a modern Hackney house. Ask on 07472 424 226 what house extensions means in practice at an E8 address of that age.
It depends on the property. Many single-storey rear and side-return extensions in E8 fall under permitted development, but size limits, previous extensions and conservation controls can push a project into needing a full application to Hackney Council. We assess your specific terrace before design, so you know which route applies and whether party wall notices are needed, before any commitment.
All of them, E8 included, along with the neighbouring parts of Hackney. GS Renovation does not price house extensions differently by postcode, and there is no travel charge within Dalston and the E8 area. Ring 07472 424 226 with your address and we will confirm immediately. The survey that follows is free and carries no obligation. Building control goes through Hackney Council wherever the property sits. Small jobs and full projects are quoted on precisely the same written terms.
