Bungalow rear extension in Halstead
Bungalow rear extension in Halstead: single-storey rear extensions that keep everything on one level. We measure the house, show you what the rules allow, price it in writing and build it.
Halstead is covered from our Essex round, including CO9. For Halstead bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Halstead?
Here is how the rules in England apply to a bungalow rear extension in Halstead.
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 Halstead like to extend?
Halstead mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
