Do you need planning permission for a side return extension in Witney?
Here is how the rules in England apply to a side return extension in Witney.
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 Witney like to extend?
Commuter semis and detached houses make up much of Witney, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Side return extension questions in Witney
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.
Can you match the brick or stone on my Witney house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.

Including OX28, and the surrounding Oxfordshire area.
Who will build my extension?
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.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
