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