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 Erith?
In Erith, 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 |
The main things that change the cost:
- Services connections
- Size and complexity of the house
- Ground conditions and foundations
- Site access and demolition
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 Erith?
Approvals for a new build home in Erith follow the rules for 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.
