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.

Do you need planning permission for a new build home in Caernarfon?
Here is how the rules work for a new build home 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.
What we handle
From survey to sign-off, the job normally involves:
- Site appraisal and feasibility
- Structural and services design
- Design and planning application
- Building control completion and warranty liaison
- Groundworks, foundations and drainage
- Superstructure, roof and windows
How long does it take?
The build itself usually takes 9 to 14 months on site for a typical house. Design and approvals come first and typically take 4 to 9 months, depending on the approval route.
