1a, Newminster Road, Cardiff, CF23 5AP
About 1a
1a is a three-bedroom detached house in Cardiff (CF23 5AP). It has a recorded floor area of 145 m² (around 1561 sq ft), construction records dating it to 1976-1982 and council tax band G. The latest certificate (April 2025) shows a D (score 57), a step below the typical UK home. The rating has held steady at D across 2 certificates since March 2009. Between certificates, hot-water efficiency went from Very Poor to Average; while wall efficiency dropped from Good to Average. The recommended improvements would push it to C (score 79).
It hasn't traded since December 2009, a hold of 16 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £457,000 sits 90.4% above the 2009 sale of £240,000. One planning record on file: a garage conversion approved in 2019. Past consents include a garage conversion, meaningful when judging how the property has evolved. At 145 m² it's 23.9% larger than the typical home in the postcode (117 m² median across 11 EPCs).
