Covering Bentley
Bentley sits 17 miles north-east of Sheffield, with Doncaster 1 miles to the south-east and Rotherham 11 miles to the south-west.
Homes in Yorkshire and the Humber
Stone-built terraces are typical of many West Yorkshire towns, while red brick dominates in Hull and much of South Yorkshire, so matching materials is a big part of designing an extension here.
What do you get with a mansard loft conversion?
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
- Staircase, insulation and fit-out
- En-suite, electrics and fire safety
How much does a mansard loft conversion cost in Bentley?
Typical ranges for mansard loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Mansard loft conversions | Guide price incl. VAT |
|---|---|
| Rear mansard | £65,000 to £85,000 |
| Front and rear (double) mansard | £80,000 to £110,000 |
How is a mansard loft conversion approved in Bentley?
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 can change the price or programme?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.

- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Questions about a mansard loft conversion in Bentley
