Do you need planning permission for a side return extension in Hetton-le-Hole?
Planning for a side return extension in Hetton-le-Hole 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 Hetton-le-Hole like to extend?
Terraces and semis are typical around Hetton-le-Hole. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Side return extension questions in Hetton-le-Hole
How much does a side return extension cost in Hetton-le-Hole?
As a guide, £2,070–£3,420 per square metre including VAT for a standard specification. For example, 2 m wide × 6 m deep (12 m²): about £25,000–£41,000 at that rate. Your written price follows the survey.
Do you handle building control in Hetton-le-Hole?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do I need planning permission for a rear extension in Hetton-le-Hole?
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.
