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 Forfar?
In Forfar, 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. Building costs in Scotland are close to the UK average, so the figures for Forfar are close to our national guide.

Do you need planning permission for a barn conversion in Forfar?
Here is how the rules work for a barn conversion 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
