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 Trowbridge?
In Trowbridge, a new build home typically costs £2,050–£3,250 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 £307,500–£487,500. Building costs in the South West are close to the UK average, so the figures for Trowbridge are close to our national guide. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (105 m²) | £215,000–£341,000 |

| Larger project (210 m²) | £430,500–£682,500 |

The main things that change the cost:
- External works and landscaping
- Services connections
- Ground conditions and foundations
- Size and complexity of the house
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 Trowbridge?
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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

How long does it take?
The build itself usually takes 9 to 14 months on site for a typical house. Allow time beforehand for drawings and approvals, usually 4 to 9 months.
