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 Lewisham?
In Lewisham, 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. We start from a UK-wide guide and adjust it for London, where labour and materials are typically about 30% above average. Design, structural calculations and council fees are extra.

|---|---|
| Smaller project (105 m²) | £273,000–£436,000 |

| Larger project (210 m²) | £546,000–£871,500 |

The main things that change the cost:
- Services connections
- Specification and energy systems
- Site access and demolition
- Size and complexity of the house
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a new build home in Lewisham?
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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
Handled as part of most new build homes:
- Groundworks, foundations and drainage
- Building control completion and warranty liaison

How long does it take?
Expect 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.
