Wraparound extension in Blacon
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Blacon and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Blacon (CH1 and CH2) as part of our Cheshire work. Wraparound projects around Blacon often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Blacon?
Here is how the rules in England apply to a wraparound extension in Blacon.
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 Blacon like to extend?
Stone and brick terraces are common around Blacon. 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 Blacon
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.
How long does a rear extension take to build in Blacon?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
Do you handle building control in Blacon?
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.
