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 Clydach?
In Clydach, 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. 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 new build home in Clydach?
Before anything is built in Clydach, we confirm which approvals apply 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Structural and services design
- Groundworks, foundations and drainage
- Site appraisal and feasibility
- Building control completion and warranty liaison
- Internal fit-out and finishes
- Mechanical and electrical installation
How long does it take?
Expect 9 to 14 months on site for a typical house. Before that, surveys, drawings and approvals usually take 4 to 9 months, longer if the council asks for changes.
