Wraparound extension in New Mills
We plan and build wraparound extensions for homeowners in New Mills. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
New Mills is covered from our Derbyshire round, including SK22. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Derbyshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in New Mills?
Planning for a wraparound extension in New Mills 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. 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 New Mills like to extend?
Red-brick terraces and semis are typical of New Mills. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.
