Do you need planning permission for a bungalow rear extension in Chaddesden?
Planning for a bungalow rear extension in Chaddesden follows the English householder rules.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it 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 Chaddesden like to extend?
Red-brick terraces and semis are typical of Chaddesden. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

FAQ
Bungalow rear extension questions in Chaddesden
Is the site visit in Chaddesden free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Chaddesden house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How deep can I extend?
The same limits as a house: 3 or 4 metres in England, more with prior approval.
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.
How long does a rear extension take to build in Chaddesden?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
