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 St Andrews?
In St Andrews, a barn conversion typically costs £1,750–£2,900 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 £262,500–£435,000. Prices in Scotland sit near the national average for this kind of work, and the range for St Andrews reflects that. Design, structural calculations and council fees are extra.

|---|---|
| Smaller project (105 m²) | £184,000–£304,500 |
| Typical project (150 m²) | £262,500–£435,000 |
| Larger project (210 m²) | £367,500–£609,000 |

Your quote will depend mainly on:
- Condition of the existing structure
- Insulation approach
- Access to the site
- Services and drainage
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a barn conversion in St Andrews?
Before anything is built in St Andrews, we confirm which approvals apply in Scotland. In Scotland converting a barn into a home usually needs planning permission (limited permitted development rights exist for some agricultural buildings), and a building warrant is needed.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
We check this for your address before design work starts, so there are no surprises later.
