What goes into a mansard loft conversion?
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.
- Roof removal and new mansard frame
- Slate cladding and lead-clad dormers
- Staircase, insulation and fit-out
