Covering Crewe
Our coverage around Crewe (CW1, CW98) also includes Winsford (7 miles to the north-west) and Kidsgrove.
Homes in the North West
Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.
What is a mansard loft conversion?
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.
- Planning application to local design guidance
- Slate cladding and lead-clad dormers
- Staircase, insulation and fit-out
How much does a mansard loft conversion cost in Crewe?
Indicative costs for mansard loft conversions. London and the South East usually sit towards the top of each range.
| Mansard loft conversions | Guide price incl. VAT |
|---|---|
| Rear mansard | £65,000 to £85,000 |
| Front and rear (double) mansard | £80,000 to £110,000 |
What approvals does a mansard loft conversion need in England?
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. Many councils publish guidance on mansard design.
What should Crewe homeowners check first?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.

What people ask before starting
Does a mansard need planning permission?
Almost always, because it changes the roof profile.
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 Crewe 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.
