What is included in a mansard loft conversion in Runcorn?
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.
- Planning application to local design guidance
- Structural design and party wall process
- Roof removal and new mansard frame

What approvals does a mansard loft conversion need in England?
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. Many councils publish guidance on mansard design.
What should I think about before starting?
- Council design guides often require natural slate and lead.
- Scaffolding and a temporary roof are usually needed.

Your questions answered
Why choose a mansard over a dormer?
A mansard gives more usable space and often fits a street better where neighbours already have one.
Will I need party wall agreements?
Very likely, as the work affects the walls shared with both neighbours on a terrace.
