The infill plots that interests us around Carmarthen
Infill gaps in Carmarthen's established streets can be among the easiest small sites to bring forward when the design respects the neighbours. As the county town of Dyfed, Carmarthen anchors the area we cover here, along with Burry Port, Llanelli and Ammanford.
- Side gardens with their own road frontage
- Corner plots within built-up areas
- Plots large enough for one or more homes with parking
- Land with or without an earlier planning history
Housing growth in Dyfed is planned through Local Development Plans, with land submitted at the candidate site stage. Llanelli, Carmarthen and the Haven towns see most demand, while flood risk under TAN 15 matters on the Loughor estuary, the coast and river valleys such as the Tywi.
