Wraparound extension in Birmingham

Birmingham sits in the West Midlands, with postcode districts including B6, B8, B19 and B23. Wraparound projects around Birmingham often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Birmingham?
Here is how the rules in England apply to a wraparound extension in Birmingham.
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 Birmingham like to extend?
Birmingham has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ
Wraparound extension questions in Birmingham
Do you handle building control in Birmingham?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
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.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Is the site visit in Birmingham free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
