About 19 Abernethy Close
19 Abernethy Close is a semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0SB). It has a recorded floor area of 73 m² (around 787 sq ft), construction records dating it to 1983-1990 and council tax band C. The latest certificate (February 2010) shows a D (score 62), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 73). The latest certificate is from February 2010, so improvements made since then won't be reflected.
It hasn't traded since April 1997, a hold of 29 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. One planning application is currently pending a decision in 2026.
