Do you need planning permission for a wraparound extension in Darlington?
Planning for a wraparound extension in Darlington 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Darlington like to extend?
Terraces and semis are typical around Darlington. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

How much does a wraparound extension cost in Darlington?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Do you handle building control in Darlington?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
