Do you need planning permission for a bungalow rear extension in Weston-super-Mare?
Planning for a bungalow rear extension in Weston-super-Mare follows the English householder rules.
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 Weston-super-Mare like to extend?
Stone-built and rendered houses are common around Weston-super-Mare, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

FAQ
Bungalow rear extension questions in Weston-super-Mare
Is the site visit in Weston-super-Mare free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Weston-super-Mare?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Do I need to move out?
Rarely; the opening into the bungalow is made late in the build.
How long does a rear extension take to build in Weston-super-Mare?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
