What is included in a mansard loft conversion in Colwyn Bay?
A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.

Do you need permission for a mansard loft conversion in Colwyn Bay?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.
What can change the price or programme?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.
