Do you need planning permission for a side return extension in Broadstone?
Whether your side return extension in Broadstone needs a planning application depends on its size, your house and any local restrictions.
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 Broadstone like to extend?

Side return extension questions in Broadstone
Can you match the brick or stone on my Broadstone house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Where does the drainage go?
Side passages often carry the soil and rainwater pipes. We survey them first and reroute them under the new floor where needed.
