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 Pembroke Dock?
In Pembroke Dock, 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 Pembroke Dock. Design, structural calculations and council fees are extra.

Do you need planning permission for a barn conversion in Pembroke Dock?
Before anything is built in Pembroke Dock, we confirm which approvals apply in 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.
What we handle
What we take care of:
- Building control completion
- Structural survey and feasibility
- Planning or prior approval application
- Services, drainage and septic or treatment plant
- Ecology and bat survey coordination
- New roof covering where needed
How long does it take?
The build itself usually takes 6 to 12 months on site depending on condition. Before that, surveys, drawings and approvals usually take 4 to 9 months, longer if the council asks for changes.
