Single-storey rear extension in Great Malvern
For homes in Great Malvern, a single-storey rear extension is often the simplest way to gain space without moving. Ground-floor space across the back of the house, usually for a kitchen, dining or family room. We take it from survey to completion certificate.
We cover Great Malvern (WR14) as part of our Worcestershire work. A depth of 3 to 4 metres keeps many single-storey rear extensions in Great Malvern within permitted development, subject to the house's planning history.

Do you need planning permission for a single-storey rear extension in Great Malvern?
Here is how the rules in England apply to a single-storey rear extension in Great Malvern.
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. 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 Great Malvern like to extend?
Great Malvern has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
