Rear and side extensions in Barking and Dagenham

The 1930s semis in this borough sit on generous plots, which suits single and double storey rear extensions, side-return infills down the passage between houses, and wrap-around designs that do both. We dig and pour the foundations, build up in blockwork or cavity brick, install any steel needed to carry the existing structure, then tie the new roof into the old.

Because interwar houses here often have wider gardens than the packed Victorian terraces closer to central London, there is frequently scope for a substantial kitchen-diner across the back. We manage the whole build, from breaking ground to plastering, so the extension reads as part of the original house rather than an obvious add-on.

Planning and permitted development in Barking and Dagenham

Many single storey rear extensions on Becontree and Dagenham semis fall under permitted development, which means no full planning application, though the work still needs building regulations approval and inspection. Larger schemes, most double storey extensions, and anything altering the front or affecting a protected setting will need a planning application to Barking and Dagenham Council.

We assess your specific property early and tell you honestly which route applies. Where the extension sits against the boundary or affects the shared wall of a semi, the Party Wall Act also comes into play. We coordinate the drawings, the council submission where needed, the party wall notices and building control into one clear programme.

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.
