Wraparound extension in Mangotsfield
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 Mangotsfield and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Mangotsfield (BS15, BS16 and BS36) as part of our Bristol and South Gloucestershire work. Wraparound projects around Mangotsfield often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Mangotsfield?
Planning for a wraparound extension in Mangotsfield follows the English householder rules.
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 Mangotsfield like to extend?
Mangotsfield has Victorian terraces nearer the centre and post-war semis on the edges. Sloping gardens are frequent, which affects floor levels and steps down to the patio.
