Side return extension in Blyth
Infilling the narrow passage beside a Victorian or Edwardian back addition. We design, get the approvals for and build side return extensions in Blyth and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Blyth (NE23 and NE24) as part of our Northumberland work. Side returns suit the Victorian and Edwardian terraces found across parts of Northumberland, where the kitchen sits in a narrow back addition.

A side return extension in Blyth is priced at £2,070–£3,420 per square metre including VAT as a guide, before kitchen fit-out and fees. 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 for a side return extension in Blyth?
Whether your side return extension in Blyth needs a planning application depends on its size, your house and any local restrictions.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Blyth like to extend?
Brick terraces, colliery houses and post-war semis make up much of Blyth. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Side return extension questions in Blyth
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How long does a rear extension take to build in Blyth?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Do you handle building control in Blyth?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Is the site visit in Blyth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Blyth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
