Do you need planning permission for a single-storey rear extension in Worcester?
The planning route for a single-storey rear extension in Worcester is set by England's householder rules and your council.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Worcester like to extend?
Red-brick terraces and 1930s semis make up much of Worcester. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

FAQ
Single-storey rear extension questions in Worcester
What postcode areas do you cover around Worcester?
Including WR1, WR2, WR3, WR4, WR5 and WR8, and the surrounding Worcestershire area.
How long does a rear extension take to build in Worcester?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
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.
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 Worcester house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
