Do you need planning permission for a two-storey rear extension in Chaddesden?
Here is how the rules in England apply to a two-storey rear extension in Chaddesden.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
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
Two-storey rear extension questions in Chaddesden
How much does a two-storey rear extension cost in Chaddesden?
As a guide, £1,750–£2,620 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £52,500–£78,500 at that rate. Your written price follows the survey.
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.
What is the 45-degree rule?
Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.
Do I need planning permission for a rear extension in Chaddesden?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
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 Chaddesden house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
