Side return extension in Wembley

Infilling the narrow passage beside a Victorian or Edwardian back addition. We design, get the approvals for and build side return extensions in Wembley and the surrounding area, with one contract from the first survey to building control sign-off.

We cover Wembley (HA0, HA9 and UB6) as part of our Greater London work. Side returns suit the Victorian and Edwardian terraces found across parts of Greater London, where the kitchen sits in a narrow back addition.

Do you need planning permission for a side return extension in Wembley?

Planning for a side return extension in Wembley follows the English householder rules.

In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.

Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Wembley like to extend?

Wembley is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.
