Single and double storey extensions in Hoxton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation designs and builds extensions on Hoxton's Victorian and Edwardian terraces, adding the space these bay-fronted homes were never given. Working across N1 and the neighbouring streets towards Shoreditch and Dalston, our team of over 30 years handles the groundworks, steels, roof and full fit-out, and guides you through whether the work is permitted development or needs a planning application to Hackney Council.

The side return is the strip of wasted outdoor space beside the rear closet wing, and infilling it is the classic Hoxton extension, squaring off a narrow galley kitchen into a wide, light-filled kitchen-diner. We dig and lay new foundations to suit the ground conditions, tie the new structure into the existing flank wall, and open up the rear with a steel goalpost frame and a roof lantern or glazed doors onto the garden.
Many single-storey rear and side-return extensions fall under permitted development, but that is never guaranteed. Homes in a conservation area, those already extended, or double-storey and wrap-around schemes often need a full planning application to Hackney Council. We assess your property first, advise on the route, prepare the drawings, and handle the building regulations separately, because the structural and thermal work needs building control sign-off whether or not planning permission is required.
Extending a Hoxton terrace starts below ground. We excavate for new foundations sized to the London clay beneath these streets, allowing for nearby trees and the shallow footings of the original Victorian build. Existing drainage runs across the rear of most of these plots, so we survey the manholes and reroute or build over the drains to Thames Water requirements, with the correct build-over agreement where a public sewer crosses the site.
Because terraced plots share boundaries on both sides, an extension almost always triggers the Party Wall Act. Digging foundations within three metres of a neighbour's wall, or building up to the boundary line, requires notice served before work begins. We manage this early so the schedule is not held up, keep the site clean and secure in these tight urban gardens, and protect the shared walls throughout the groundworks and the build.
Hoxton homeowners choose GS Renovation because we deliver the whole extension under one roof, from the first foundation to the final coat of paint. You deal with one accountable team for the design, the planning and building control route, the steelwork and the finish. With 30+ years building on Hackney's terraces, we understand the plots, the party walls and the council process.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
We price each Hoxton project individually, because the cost of house extensions depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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.
Most house extensions projects in Hoxton take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.
Because we manage every trade in-house, your Hoxton project stays consistent and accountable from first fix to finish. Add transparent pricing, full insurance and real aftercare, and it is easy to see why Hoxton clients recommend us.
Many single-storey rear extensions in Hoxton fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full planning permission. We assess your property and manage both the planning application and building control.
Yes. A large share of Hoxton's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
It depends on the property. Many single-storey side-return and rear extensions in Hoxton are permitted development, but if your home is in a conservation area, has already been extended, or you want a double-storey or wrap-around design, a planning application to Hackney Council is usually needed. We check the constraints on your specific address before starting and handle whichever route applies.
We cover the whole of Hoxton and the N1 area and the surrounding East London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
