Planning and building rules in Stonehaven
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 Stonehaven homeowners check first?
- Groundwater levels drive the waterproofing design and cost.
