Side-return and rear extensions in Acton

The classic Acton project fills in the side return, the narrow alley beside the rear closet wing, to widen a cramped galley kitchen into a bright open-plan space. We dig and lay the foundations, build up in matching brick, install the steel beams that carry the original rear wall, and tie the new roof into the existing terrace so it looks like it always belonged there.

Wrap-around extensions combine the side return with a rear projection to make the most of the plot, while double-storey schemes add a bedroom above. On these solid-walled W3 terraces we pay close attention to damp-proofing, ground levels and how the new structure meets the period brickwork, so the addition performs as well as it looks.

Planning and party walls in Ealing borough

Whether your Acton extension is permitted development or needs a full planning application depends on the property. Many single-storey rear and side-return extensions fall under permitted development, but corner plots, larger footprints, and any home in a conservation area or with an Article 4 direction may need permission from Ealing Council. We assess your specific house before any drawings are finalised.

Extending up to or across a boundary on a terraced W3 street almost always engages the Party Wall Act, since your neighbours share the flank wall. We guide you through the notices alongside the building regulations approval that the foundations, steel and drainage all require. The structural sign-off and the planning route are two separate things, and we keep both on track.

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.
