Wraparound extension in Berwick-upon-Tweed
For homes in Berwick-upon-Tweed, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
Berwick-upon-Tweed is covered from our Northumberland round, including TD15. In Berwick-upon-Tweed 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 Berwick-upon-Tweed?
Here is how the rules in England apply to a wraparound extension in Berwick-upon-Tweed.
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 Berwick-upon-Tweed like to extend?
Brick terraces, colliery houses and post-war semis make up much of Berwick-upon-Tweed. Former mining areas often need a coal mining risk check before foundations are designed.
