This is a very useful guest post by Skylark Garden Rooms explaining the Permitted Development rules when building a garden room in Scotland.
Householder permitted development
Garden Rooms and Certificates of Lawfulness
A Certificate of Lawfulness is different to Planning Permission, but does give you proof that the building work is legal, as is the intended use of the building.
Householder Permitted Development Tool
A must for anyone considering buying a garden room, is a visit to the governments Planning Portal, they have a useful tool for indentifying if your garden room needs planning permission, or falls within the householders permitted development rights.
[caption id="attachment_1910" align="alignleft" width="300" caption="Screenshot of listed building rules"]The tool shows various different scenarios in 3D, for instance if you live in a listed building the tool clearly shows that outbuildings don’t fall within permitted development rules so planning permission will be required.
An easier format to understand than a list of rules, you can access the tool by clicking here.
