Do you need planning permission for a wraparound extension in Annfield Plain?
Here is how the rules in England apply to a wraparound extension in Annfield Plain.
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 Annfield Plain like to extend?
Brick terraces, colliery houses and post-war semis make up much of Annfield Plain. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Wraparound extension questions in Annfield Plain
How long does a rear extension take to build in Annfield Plain?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do I need planning permission for a rear extension in Annfield Plain?
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.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
How much does a wraparound extension cost in Annfield Plain?
As a guide, £1,980–£3,240 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £43,500–£71,500 at that rate. Your written price follows the survey.
Do you handle building control in Annfield Plain?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
