Covering Ilkeston
We work in Ilkeston (DE7) and the places around it, including Heanor, Long Eaton and Ripley.
Homes in the East Midlands
Housing in the East Midlands includes Victorian terraces, inter-war semis and newer estates, with stone-built villages in some areas where conservation controls apply.
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
- Roof removal and new mansard frame

Do you need permission for a mansard loft conversion in Ilkeston?
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 Ilkeston homeowners check first?
- Council design guides often require natural slate and lead.
- Scaffolding and a temporary roof are usually needed.
From first call to completion
- 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.
- 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.
Your questions answered
How long does a mansard take?
Around 10 to 14 weeks on site after planning approval.
Will I need party wall agreements?
Very likely, as the work affects the walls shared with both neighbours on a terrace.
Can you visit a house in Ilkeston 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.
