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 Chelsea?
In Chelsea, a small housing development typically costs £2,350–£3,500 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 £940,000–£1,400,000. 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.
| Size or type | Guide range |

| Larger project (560 m²) | £1,316,000–£1,960,000 |
| Rate per m² | £2,350–£3,500 |
The main things that change the cost:
- Roads, sewers and adoption agreements
- Specification
- Number and size of homes
- Planning conditions and obligations
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a small housing development in Chelsea?
Whether you need planning permission depends on your house and its location 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Warranty and building control inspections
- Pre-construction cost plan
- Utility connections
- Design development and discharge of conditions
- External works and landscaping
- House construction to building regulations
How long does it take?
Allow 12 to 24 months depending on scheme size. Before that, surveys, drawings and approvals usually take 6 to 12 months, longer if the council asks for changes.

Victorian and Edwardian terraces dominate many London streets, which is why side return, wraparound and mansard projects are so common here.
