Do you need planning permission for a bungalow rear extension in Cramlington?
The planning route for a bungalow rear extension in Cramlington is set by England's householder rules and your council.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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. 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 Cramlington like to extend?
Terraces and semis are typical around Cramlington. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
