Do you need planning permission for a side return extension in Stockton-on-Tees?

Here is how the rules in England apply to a side return extension in Stockton-on-Tees.

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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Stockton-on-Tees like to extend?

FAQ

Side return extension questions in Stockton-on-Tees

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.

Can you match the brick or stone on my Stockton-on-Tees house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Where does the drainage go?

Side passages often carry the soil and rainwater pipes. We survey them first and reroute them under the new floor where needed.

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.

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.

Do I need a party wall agreement?

In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
