Do you need planning permission for a bungalow rear extension in Newbury?
Here is how the rules in England apply to a bungalow rear extension in Newbury.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 Newbury like to extend?
Newbury has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

FAQ
Bungalow rear extension questions in Newbury
Can you match the brick or stone on my Newbury house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How much does a bungalow rear extension cost in Newbury?
As a guide, £2,070–£3,360 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £25,000–£40,500 at that rate. Your written price follows the survey.

Rarely; the opening into the bungalow is made late in the build.
Do I need planning permission for a rear extension in Newbury?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
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.
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.
