Do you need planning permission for a single-storey rear extension in Clydebank?

The planning route for a single-storey rear extension in Clydebank is set by Scotland's householder rules and your council.

Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.

Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.

Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.

What are homes in Clydebank like to extend?

Clydebank has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.
