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 County Londonderry?
In County Londonderry, a small housing development typically costs £1,550–£2,300 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 £620,000–£920,000. We start from a UK-wide guide and adjust it for Northern Ireland, where labour and materials are typically about 14% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (280 m²) | £434,000–£644,000 |
| Typical project (400 m²) | £620,000–£920,000 |
| Larger project (560 m²) | £868,000–£1,288,000 |
| Rate per m² | £1,550–£2,300 |

- Ground conditions

Do you need planning permission for a small housing development in County Londonderry?
Before anything is built in County Londonderry, we confirm which approvals apply in Northern Ireland. In Northern Ireland small schemes need planning permission and building control approval, with road adoption agreed with DfI Roads where relevant.
In Northern Ireland building control approval comes from the council, usually through a full plans application or a building notice, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
