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 Armagh?
In Armagh, a barn conversion typically costs £1,550–£2,600 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 £232,500–£390,000. Building costs in Northern Ireland run about 14% below the UK average, and the figures for Armagh are adjusted to reflect that.
