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 Deeside?
In Deeside, a barn conversion typically costs £1,650–£2,750 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 £247,500–£412,500. Building costs in Wales run about 8% below the UK average, and the figures for Deeside are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a barn conversion in Deeside?
Approvals for a barn conversion in Deeside follow the rules for Wales. In Wales converting a barn into a home needs full planning permission; there is no equivalent of the English Class Q route.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
