Single-storey rear extension in Wellington
For homes in Wellington, 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.
Wellington is covered from our Shropshire round, including TF1 and TF5. A depth of 3 to 4 metres keeps many single-storey rear extensions in Wellington within permitted development, subject to the house's planning history.

Do you need planning permission for a single-storey rear extension in Wellington?
The planning route for a single-storey rear extension in Wellington 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.
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 Wellington like to extend?
Red-brick terraces and 1930s semis make up much of Wellington. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
