Do you need planning permission for a wraparound extension in Ashton-under-Lyne?
The planning route for a wraparound extension in Ashton-under-Lyne is set by England's householder rules and your council.
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 Ashton-under-Lyne like to extend?
Stone and brick terraces are common around Ashton-under-Lyne. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Wraparound extension questions in Ashton-under-Lyne
Do you handle building control in Ashton-under-Lyne?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
What postcode areas do you cover around Ashton-under-Lyne?
Including M34, M43, OL6, OL7, SK14 and SK16, and the surrounding Greater Manchester area.
Can you match the brick or stone on my Ashton-under-Lyne house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
