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 Carmarthen?
In Carmarthen, 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. That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a small housing development in Carmarthen?
Approvals for a small housing development in Carmarthen follow the rules for 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Utility connections
- External works and landscaping
- Handover packs for each home
- Design development and discharge of conditions
- Warranty and building control inspections
- Groundworks, roads and drainage
How long does it take?
Allow 12 to 24 months depending on scheme size. Allow time beforehand for drawings and approvals, usually 6 to 12 months.
Building in Carmarthen
Wales has many terraced valley streets, stone cottages and post-war estates, so extension designs are shaped by slopes, materials and local character.
From SA31 outwards, we take on projects throughout Carmarthen and the surrounding parts of Dyfed.
