What is a barn conversion?
A barn conversion turns an agricultural or rural building into a home while keeping its character: the brick or stone walls, roof timbers and large openings. It involves structural repair, insulation, new services and often a new floor slab.
How much does a barn conversion cost in Wilmslow?
In Wilmslow, a barn conversion typically costs £1,700–£2,800 per m² of floor area, including VAT at usually 5% (reduced rate for creating a new dwelling). For a typical 150 m² project that is roughly £255,000–£420,000. We start from a UK-wide guide and adjust it for the North West, where labour and materials are typically about 6% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (105 m²) | £178,500–£294,000 |
| Typical project (150 m²) | £255,000–£420,000 |
| Larger project (210 m²) | £357,000–£588,000 |
| Rate per m² | £1,700–£2,800 |
The biggest cost drivers are:
- Glazing and finishes
- Condition of the existing structure
- Planning conditions and ecology
- Insulation approach

Do you need planning permission for a barn conversion in Wilmslow?
Before anything is built in Wilmslow, we confirm which approvals apply in England. In England converting an agricultural building into a home needs either full planning permission or prior approval under Class Q of the permitted development rules, which limits floor space and the number of homes. Listed barns also need listed building consent.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
We check this for your address before design work starts, so there are no surprises later.

Yes. A barn conversion needs planning permission or, in England only, prior approval under the agricultural permitted development rules where the building qualifies. Listed barns also need listed building consent.

A sewage treatment plant can be installed, subject to the environmental regulator’s rules where you live.
