Do you need planning permission for a wraparound extension in Newmarket?
The planning route for a wraparound extension in Newmarket is set by England's householder rules and your council.
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 Newmarket like to extend?
Newmarket mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
