Do you need planning permission for a side return extension in Sidmouth?
Here is how the rules in England apply to a side return extension in Sidmouth.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Sidmouth like to extend?
Stone-built and rendered houses are common around Sidmouth, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

Side return extension questions in Sidmouth

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
