Which leak investigations cover the Carmarthen area of Carmarthenshire?
The county's market-town setting on the Towy includes the historic Picton Terrace area and university accommodation. An enquiry should distinguish the occupied rooms from the surrounding landmark or neighbourhood.
Carmarthen's built-up-area Census results for 2021 show a close balance between detached accommodation, 2,300 units at 28.4%, and semi-detached accommodation, 2,335 at 28.8%. Terraced units number 1,955, with a 24.2% share; flats, maisonettes or apartments number 1,505, with 18.6%.
Picton Terrace's appraisal describes formal residential terraces and their garden plots, placing the area within Carmarthen's historic fabric. When ceiling marks appear in such premises, identify the floor above and any changed use of that space. A frontage description alone cannot locate the water's origin.
Carmarthen includes university-managed accommodation as well as ordinary household tenures. For concealed plumbing in an occupied building, say which kitchen or bathroom is involved and whether another person controls entry to adjacent rooms. The university location is separate evidence from the town's general rental statistics.
