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 Sunbury-on-Thames?
The approval route for Sunbury-on-Thames is set by planning law in England. In England a new home needs full planning permission (or permission in principle followed by technical details consent). Councils assess design, access, neighbours and drainage, and the Community Infrastructure Levy may apply, though self-builders can claim an exemption before starting.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued 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:
- Internal fit-out and finishes
- Building control completion and warranty liaison
- Site appraisal and feasibility

- Structural and services design
- Superstructure, roof and windows
How long does it take?
Allow 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.
