What is a small housing development?

A small housing development is a scheme of a few new homes, typically two to nine, on a single site. We work with landowners, small developers and investors to build schemes that already have planning permission, or help take a site through planning first.
How much does a small housing development cost in Swanley?
In Swanley, a small housing development typically costs £2,000–£3,000 per m² of floor area (build cost), including VAT at 0% (zero-rated for qualifying new dwellings). For a typical 400 m² project that is roughly £800,000–£1,200,000. We start from a UK-wide guide and adjust it for the South East, where labour and materials are typically about 12% above average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (280 m²) | £560,000–£840,000 |
| Typical project (400 m²) | £800,000–£1,200,000 |
| Larger project (560 m²) | £1,120,000–£1,680,000 |
| Rate per m² | £2,000–£3,000 |
The main things that change the cost:
- Number and size of homes
- Roads, sewers and adoption agreements
- Ground conditions
- Site access and phasing
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a small housing development in Swanley?
The approval route for Swanley is set by planning law in England. In England small schemes need full planning permission and may involve a section 106 agreement, the Community Infrastructure Levy, highways and drainage approvals, and biodiversity net gain where it applies.
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.
