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 Carshalton?
In Carshalton, 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 Carshalton.

Do you need planning permission for a small housing development in Carshalton?
The approval route for Carshalton 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
