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
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.
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"][/caption]
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.
