Do you need planning permission for a single-storey rear extension in The Boldons?
Here is how the rules in England apply to a single-storey rear extension in The Boldons.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 The Boldons like to extend?
Brick terraces, colliery houses and post-war semis make up much of The Boldons. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Single-storey rear extension questions in The Boldons
What postcode areas do you cover around The Boldons?
Including NE32, NE35 and NE36, and the surrounding Tyne and Wear area.
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.
Will the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.
Do you handle building control in The Boldons?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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 you match the brick or stone on my The Boldons house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
