Do you need planning permission for a wraparound extension in Lancing?
Here is how the rules in England apply to a wraparound extension in Lancing.
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 Lancing like to extend?
Commuter semis and detached houses make up much of Lancing, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Wraparound extension questions in Lancing
How long does a rear extension take to build in Lancing?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
Is it worth it over a side return alone?
If you want a dining table and a sofa as well as the kitchen, usually yes.
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.
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.
Do you handle building control in Lancing?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
