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 Blackheath?
Here is how the rules work for a new build home 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Groundworks, foundations and drainage
- Mechanical and electrical installation
- Design and planning application
- Internal fit-out and finishes
- Site appraisal and feasibility
- Building control completion and warranty liaison
How long does it take?
Allow 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.
