Do you need planning permission for a bungalow rear extension in Luton?
Whether your bungalow rear extension in Luton needs a planning application depends on its size, your house and any local restrictions.
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 Luton like to extend?
Luton mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here. For bungalows in Bedfordshire, a rear extension is the usual way to add space without adding stairs.

FAQ
Bungalow rear extension questions in Luton
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Do you handle building control in Luton?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
How deep can I extend?
The same limits as a house: 3 or 4 metres in England, more with prior approval.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Luton house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
