Homes in the North West
Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.
What does a mansard loft conversion involve?
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
- Slate cladding and lead-clad dormers
How much should I budget for a mansard loft conversion?
Typical ranges for mansard loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

| Rear mansard | £65,000 to £85,000 |

Do you need permission for a mansard loft conversion in Royton?
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 should I think about before starting?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Almost always, because it changes the roof profile.

Around 10 to 14 weeks on site after planning approval.
Can you visit a house in Royton to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
