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 Nailsea?
In Nailsea, 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 Nailsea are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for a new build home in Nailsea?
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.
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
- Internal fit-out and finishes
- Mechanical and electrical installation
- Building control completion and warranty liaison
How long does it take?
The build itself usually takes 9 to 14 months on site for a typical house. Design and approvals come first and typically take 4 to 9 months, depending on the approval route.
