Homes in Yorkshire and the Humber

Across Yorkshire and the Humber, older stone and brick terraces sit alongside inter-war semis and newer estates, and dormers and rear extensions are designed to suit each.

What does a mansard loft conversion involve?

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

Do you need permission for a mansard loft conversion in Leeds?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.

What can affect a mansard loft conversion?

  • A mansard nearly always involves party walls on both sides of a terrace.
  • The roof is open for longer than with a dormer, so weather protection matters.

How does the project run?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Very likely, as the work affects the walls shared with both neighbours on a terrace.
