Wraparound extensions in Northumberland
An L-shaped extension that fills the side return and runs across the back. We design and build rear extensions across Northumberland, from Blyth and Cramlington to Ashington, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Northumberland where a side return alone would leave the room too narrow. Terraces and semis are typical around Northumberland. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.
How much does a wraparound extension cost in Northumberland?
Guide prices for a wraparound extension in Northumberland start from our North East England rate of £1,980–£3,240 per square metre, including VAT. North East prices are among the lowest in our range; former mining ground is the main foundation variable.

These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Northumberland?
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.

FAQ
Questions people ask
Does a wraparound need planning permission?
Often yes, because the side and rear parts are judged together. Some fit within permitted development; we check before drawing.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can the corner be all glass?
Yes, with a steel or aluminium post or a structural glass corner. It needs careful thermal detailing to meet Building Regulations.
Do you cover all of Northumberland?
We cover 10 towns and districts in Northumberland, including Blyth, Cramlington and Ashington.
