What is included in a mansard loft conversion in Ripley?
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.
- Structural design and party wall process
- Roof removal and new mansard frame
- Slate cladding and lead-clad dormers

How is a mansard loft conversion approved in Ripley?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.
What can change the price or programme?
- 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?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Mansard loft conversions: common questions
Does a mansard need planning permission?
Almost always, because it changes the roof profile.
Why choose a mansard over a dormer?
A mansard gives more usable space and often fits a street better where neighbours already have one.
