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.

Headroom of about 2.1 m or more is needed, which may mean lowering the floor.
