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 Chelsea?
In Chelsea, 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. Prices across London are typically 30% above the UK average for this kind of work, which is reflected in the range for Chelsea. Design, structural calculations and council fees are extra.

Do you need planning permission for a new build home in Chelsea?
Whether you need planning permission depends on your house and its location 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.
We check this for your address before design work starts, so there are no surprises later.
