Do you need planning permission for a bungalow rear extension in Stanley?

Here is how the rules in England apply to a bungalow rear extension in Stanley.

English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

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 Stanley like to extend?

Brick terraces, colliery houses and post-war semis make up much of Stanley. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ

Bungalow rear extension questions in Stanley

What postcode areas do you cover around Stanley?

Including DH9, and the surrounding County Durham area.

Is the site visit in Stanley free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

Do I need to move out?

Rarely; the opening into the bungalow is made late in the build.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

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 Stanley house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
