Wraparound extension in Whitby
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 Whitby and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Whitby (YO21 and YO22) as part of our North Yorkshire work. In Whitby we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

Do you need planning permission for a wraparound extension in Whitby?
The planning route for a wraparound extension in Whitby 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. 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 Whitby like to extend?
Stone terraces and brick semis are typical of Whitby. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.
