Do you need planning permission for a wraparound extension in Blandford Forum?
Here is how the rules in England apply to a wraparound extension in Blandford Forum.
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 Blandford Forum like to extend?
Stone-built and rendered houses are common around Blandford Forum, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
