House Extensions Ilford

Single and double storey extensions in Ilford. Trusted, professional, 30+ years' hands-on experience.

Ilford's bay-fronted Victorian and Edwardian terraces, with their rear closet wings and side returns, extend beautifully. GS Renovation has spent over 30 years adding space to IG1 homes, from a modest kitchen extension to a full wrap-around. We handle the foundations, the steel, the roof and the fit-out, and we guide you through Redbridge Council's planning rules.

Side-return and rear extensions in Ilford

The side return on an Ilford terrace, that narrow strip beside the closet wing, is often dead space. Filling it in and extending to the rear turns a cramped galley kitchen into an open-plan kitchen-diner that runs the full width of the house. We dig and pour the foundations to the required depth, allowing for the mature trees around Valentines Park and Wanstead Park that can affect ground conditions on clay soils.

Steel beams tie the new opening back into the original structure, sized by an engineer and inspected by building control. We build up the walls, form the roof, whether a flat roof with rooflights or a pitched addition, and weather it in before moving inside. Where the extension sits against a neighbour's boundary, which is common on these tightly packed IG1 plots, the Party Wall Act applies and we serve the notices for you.

Planning permission for Ilford extensions

Many single-storey rear extensions in Ilford fall under permitted development, meaning no full planning application is needed provided you stay within the size, height and materials limits. A double-storey extension, a build close to the front, or work on a property in one of Redbridge's conservation areas usually needs planning permission from Redbridge Council. We assess your specific house first and tell you honestly which route applies before any drawings are commissioned.

Whichever route your extension takes, the building work itself must meet building regulations, covering foundations, structure, insulation, drainage and fire safety, all inspected as we go. We can recommend architects and structural engineers, or work to plans you already hold. From the first trench to the final coat of paint, one GS Renovation team runs the site, so you are not left chasing separate trades across a half-finished IG1 extension.

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.

Do I need planning permission for an extension in Ilford?

Do you work on Victorian and Edwardian terraced homes in Ilford?

Yes. A large share of Ilford'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.

Will my Ilford rear extension need planning permission or is it permitted development?

It depends on the property. Many single-storey rear extensions on Ilford terraces are permitted development if they stay within the depth, height and materials limits. Larger, double-storey or front extensions, and homes in a Redbridge conservation area, usually need planning permission from the council. Either way it must meet building regulations. We check your house and confirm the route before you spend on drawings.
