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 Ewell?
In Ewell, a new build home typically costs £2,250–£3,600 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 £337,500–£540,000. We start from a UK-wide guide and adjust it for the South East, where labour and materials are typically about 12% above average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (105 m²) | £236,000–£378,000 |
| Typical project (150 m²) | £337,500–£540,000 |
| Larger project (210 m²) | £472,500–£756,000 |
| Rate per m² | £2,250–£3,600 |
What moves the price most:
- Specification and energy systems
- Size and complexity of the house
- Ground conditions and foundations
- Site access and demolition
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a new build home in Ewell?
Before anything is built in Ewell, we confirm which approvals apply 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
On a typical new build home we handle:
- Mechanical and electrical installation
- Building control completion and warranty liaison
- Structural and services design
- Design and planning application
- Site appraisal and feasibility
- Groundworks, foundations and drainage
How long does it take?
Expect 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.
