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