Do you need planning permission for a bungalow rear extension in Braintree?
The planning route for a bungalow rear extension in Braintree 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Braintree like to extend?
Braintree mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

Bungalow rear extension questions in Braintree

Yes. We visit, measure up and talk through the options with no cost and no obligation.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
