How is a basement conversion approved in Dumfries and Galloway?

Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.

In Scotland new basements and external lightwells normally need planning permission; all basement work needs a building warrant first.

What can change the price or programme?

Groundwater levels drive the waterproofing design and cost.
