What is a new build home?
A new build home is a house built from the ground up on a cleared plot, a garden plot or a replacement-dwelling site. We work with plot owners and self-builders to design, gain approvals and build the house, either to a fixed design or from initial ideas.
How much does a new build home cost in Colwyn Bay?
In Colwyn Bay, a new build home typically costs £1,850–£2,950 per m² of floor area (build cost), including VAT at 0% (zero-rated for qualifying new dwellings). For a typical 150 m² project that is roughly £277,500–£442,500. That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average.

Do you need planning permission for a new build home in Colwyn Bay?
Whether you need planning permission depends on your house and its location in Wales. In Wales a new home needs full planning permission. Welsh building regulations require automatic fire suppression (sprinklers) in new homes, and sustainable drainage approval from the council’s SuDS approval body is needed for most new buildings.
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.
