What is a mansard loft conversion?
A mansard loft conversion rebuilds the roof with a nearly vertical slope (about 72 degrees) and a flat top, effectively adding a new storey. Small dormer windows sit within the steep slope. Mansards are common on period terraces in towns and cities.

Do you need planning permission for a mansard loft conversion in Coatbridge?
The approval route for Coatbridge is set by planning law in Scotland. In Scotland a mansard needs planning permission and a building warrant.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- New roof structure, slate or tile covering and lead work
- Building control sign-off
- Dormer windows
- Structural design and calculations
- Insulation, electrics, plumbing and plastering
- Planning drawings and application
How long does it take?
Expect 9 to 12 weeks on site, after planning approval. Design and approvals come first and typically take 3 to 4 months, depending on the approval route.
