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 Southampton?
In Southampton, 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. The guide for Southampton reflects typical costs in the South East, roughly 12% above the UK-wide figure. Design, structural calculations and council fees are extra.

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 small housing development in Southampton?
Approvals for a small housing development in Southampton follow the rules for 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.
What we handle
From survey to sign-off, the job normally involves:
- Groundworks, roads and drainage
- Handover packs for each home
- Design development and discharge of conditions
- Warranty and building control inspections
- House construction to building regulations
- External works and landscaping
How long does it take?
The build itself usually takes 12 to 24 months depending on scheme size. Design and approvals come first and typically take 6 to 12 months, depending on the approval route.
