What do you get with a basement conversion?

A basement conversion turns an existing cellar into dry, usable rooms, or excavates a new basement under a house. Converting an existing cellar is far simpler and cheaper than digging a new one, and often does not need planning permission.

  • Damp and structural survey
  • Lightwells and windows for daylight and escape

What approvals does a basement conversion need in Scotland?

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 should I think about before starting?

  • Groundwater levels drive the waterproofing design and cost.
  • A pump for the drainage system needs a battery back-up.
