Do you need permission for a basement conversion in Perth?

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.

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.

How does the project run?

  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
