Do you need planning permission for a kitchen-diner rear extension in Stourbridge?
Here is how the rules in England apply to a kitchen-diner rear extension in Stourbridge.
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.
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. 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 Stourbridge like to extend?
Red-brick terraces and 1930s semis make up much of Stourbridge. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
