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 Lanarkshire?
In Lanarkshire, 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 Lanarkshire reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a barn conversion in Lanarkshire?
Before anything is built in Lanarkshire, 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
