What is a mansard loft conversion?

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.

What approvals does a mansard loft conversion need in Wales?

Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.

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 should I think about before starting?

The roof is open for longer than with a dormer, so weather protection matters.
Council design guides often require natural slate and lead.
