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 Clapham?
In Clapham, 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. Building costs in London run about 30% above the UK average, and the figures for Clapham are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a new build home in Clapham?
Before anything is built in Clapham, 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
On a typical new build home we handle:
- Groundworks, foundations and drainage
- Site appraisal and feasibility
- Internal fit-out and finishes
- Design and planning application
- Mechanical and electrical installation
- Superstructure, roof and windows
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.
