Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.

What is included in a mansard loft conversion in Porthcawl?

Mansards are a bigger structural job than other conversions because the roof is largely rebuilt. They normally need planning permission, and many councils have design guides setting the angle, materials and window style. We prepare the design to those guides and build in slate, lead and timber or approved alternatives.

What approvals does a mansard loft conversion need in Wales?

In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.

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 affect a mansard loft conversion?

Council design guides often require natural slate and lead.
Scaffolding and a temporary roof are usually needed.
