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 Clydach?
In Clydach, 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. Prices across Wales are typically 8% below the UK average for this kind of work, which is reflected in the range for Clydach. Design, structural calculations and council fees are extra.

Do you need planning permission for a barn conversion in Clydach?
Approvals for a barn conversion in Clydach 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
