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

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

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. 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 West Bromwich like to extend?

West Bromwich has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build. For bungalows in the West Midlands, a rear extension is the usual way to add space without adding stairs.
