Side return extension in Bishop Auckland
For homes in Bishop Auckland, a side return extension is often the simplest way to gain space without moving. Infilling the narrow passage beside a Victorian or Edwardian back addition. We take it from survey to completion certificate.
Bishop Auckland is covered from our County Durham round, including DL4 and DL14. In Bishop Auckland we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Do you need planning permission for a side return extension in Bishop Auckland?
Whether your side return extension in Bishop Auckland 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 Bishop Auckland like to extend?
Brick terraces, colliery houses and post-war semis make up much of Bishop Auckland. Former mining areas often need a coal mining risk check before foundations are designed.

Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.

Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Can you match the brick or stone on my Bishop Auckland house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
