Extension in South Staffordshire
Do you need planning permission for a single-storey extension in South Staffordshire? Here is what the permitted development rules say, how South Staffordshire Council’s designations change them, and what decides an application, grounded in the official guidance and quoted verbatim.

Do you need planning permission for a single-storey extension in South Staffordshire?
Many single-storey rear extensions are permitted development under Class A, within set limits on depth, height and how much of the garden they cover, so no planning application is needed. In South Staffordshire this matters: the borough has 19 conservation areas and 15 Article 4 directions, and inside those the permitted development route narrows or is removed, so a single-storey extension can need a full application where it would not two streets away.

|---|---|
| Conservation areas | 19 |

What South Staffordshire weighs
Where an application is needed, design does the deciding: depth against the neighbouring rear walls, loss of light, roof form, and materials against the parent building.
