Construction Trends in Carmarthenshire
Carmarthen is the focus of the county's biggest housing growth, with housebuilder Lovell Partnerships applying to build 84 homes at Ffordd Pendre on the western edge of town, part of a much larger site allocated for 1,100 homes, a school, and employment land. The council has approved a five year capital programme worth 150 million pounds through to 2030/31, while the Development Bank of Wales has committed over 7.5 million pounds to schemes including a third phase at Maes y Teirw in Carmarthen and Phase 3 of the Priory Fields development in St Clears. The council's own programme has delivered more than 150 affordable council homes in recent years, including conversions in Carmarthen and a new scheme in Burry Port. Away from these schemes, established towns keep a steady flow of extensions and loft conversions.
