Do you need planning permission for a bungalow rear extension in Yarm?
Here is how the rules in England apply to a bungalow rear extension in Yarm.
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 Yarm like to extend?
Brick terraces, colliery houses and post-war semis make up much of Yarm. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Bungalow rear extension questions in Yarm
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 you handle building control in Yarm?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
How long does a rear extension take to build in Yarm?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
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.
