An L-shaped extension that fills the side return and runs across the back. Rear extensions in County Durham: we cover 16 towns including Darlington, Hartlepool and Stockton-on-Tees, with design, approvals and the build under one contract.
Wraparound projects around Darlington often involve two neighbours, so we start the party wall conversations early. Terraces and semis are typical around County Durham. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

Do you need planning permission in County Durham?
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.

FAQ
Questions people ask
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can the corner be all glass?
Yes, with a steel or aluminium post or a structural glass corner. It needs careful thermal detailing to meet Building Regulations.
