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 Annan?
In Annan, 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 Annan reflects that.
