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 Caerphilly?
In Caerphilly, a small housing development typically costs £1,650–£2,500 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 £660,000–£1,000,000. We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (280 m²) | £462,000–£700,000 |
| Typical project (400 m²) | £660,000–£1,000,000 |
| Larger project (560 m²) | £924,000–£1,400,000 |
| Rate per m² | £1,650–£2,500 |
The biggest cost drivers are:
- Ground conditions
- Planning conditions and obligations
- Roads, sewers and adoption agreements
- Specification
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 Caerphilly?
Whether you need planning permission depends on your house and its location in Wales. In Wales small schemes need full planning permission and, for most new buildings, sustainable drainage approval from the SuDS approval body. New homes must have sprinklers.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
