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 Purley?
In Purley, 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. Building costs in London run about 30% above the UK average, and the figures for Purley are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a small housing development in Purley?
Before anything is built in Purley, we confirm which approvals apply 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

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.
