Do you need planning permission for a terraced house rear extension in Wigan?
Planning for a terraced house rear extension in Wigan follows the English householder rules.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
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 Wigan like to extend?
Stone and brick terraces are common around Wigan. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Terraced house rear extension questions in Wigan
Do you handle building control in Wigan?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
What postcode areas do you cover around Wigan?
Including WN1, WN2, WN3, WN5 and WN6, and the surrounding Greater Manchester area.
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
How long does a rear extension take to build in Wigan?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
