Bungalow rear extension in Witney
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Witney and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Witney (OX28) as part of our Oxfordshire work. For Witney 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 Witney?
Planning for a bungalow rear extension in Witney follows the English householder rules.
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 Witney like to extend?
Commuter semis and detached houses make up much of Witney, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Bungalow rear extension questions in Witney
Can you match the brick or stone on my Witney house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
