About 19 Canopus Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
19 Canopus Close is a semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 1NR). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (February 2009) shows a C (score 76), near the top of the C band. The latest certificate is from February 2009, so improvements made since then won't be reflected.
Untraded for 17 years, with the last transfer in July 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £248,000 sits 86.5% above the 2009 sale of £133,000. One planning record on file: an extension approved in 2014.
