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 Penarth?
In Penarth, 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. We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (105 m²) | £194,000–£310,000 |
| Typical project (150 m²) | £277,500–£442,500 |
| Larger project (210 m²) | £388,500–£619,500 |
| Rate per m² | £1,850–£2,950 |
The biggest cost drivers are:
- Size and complexity of the house
- Services connections
- Site access and demolition
- Specification and energy systems
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a new build home in Penarth?
The approval route for Penarth is set by planning law 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
