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 Finchley?
In Finchley, a new build home typically costs £2,600–£4,150 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 £390,000–£622,500. We start from a UK-wide guide and adjust it for London, where labour and materials are typically about 30% above average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (105 m²) | £273,000–£436,000 |
| Typical project (150 m²) | £390,000–£622,500 |
| Larger project (210 m²) | £546,000–£871,500 |
| Rate per m² | £2,600–£4,150 |
What moves the price most:
- Ground conditions and foundations
- Size and complexity of the house
- Site access and demolition
- External works and landscaping
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 Finchley?
Whether you need planning permission depends on your house and its location 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.
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:
- Design and planning application
- Site appraisal and feasibility
- Superstructure, roof and windows
- Groundworks, foundations and drainage
- Building control completion and warranty liaison
- Mechanical and electrical installation
How long does it take?
Build time is typically 9 to 14 months on site for a typical house. Allow time beforehand for drawings and approvals, usually 4 to 9 months.
