Do you need planning permission for a bungalow rear extension in Berwick-upon-Tweed?
Here is how the rules in England apply to a bungalow rear extension in Berwick-upon-Tweed.
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 Berwick-upon-Tweed like to extend?
Terraces and semis are typical around Berwick-upon-Tweed. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Bungalow rear extension questions in Berwick-upon-Tweed
Can you match the brick or stone on my Berwick-upon-Tweed house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.

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.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
