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 Southampton?
In Southampton, 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. That range is adjusted for the South East, where domestic building work typically costs around 12% above the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a new build home in Southampton?
Approvals for a new build home in Southampton 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
From survey to sign-off, the job normally involves:
- Superstructure, roof and windows
- Internal fit-out and finishes
- Site appraisal and feasibility
- Structural and services design
- Mechanical and electrical installation
- Groundworks, foundations and drainage
How long does it take?
Build time is typically 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.
