About 9 Gwern Hafren
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
9 Gwern Hafren is a mid-terrace house in Cardiff (CF11 9EY). It has a recorded floor area of 66 m² (around 710 sq ft) and council tax band E. The latest certificate (February 2009) returns a high B (score 86), putting the home a stone's throw from an A rating. The latest certificate is from February 2009, so improvements made since then won't be reflected. At 66 m² this is the 11th smallest of 15 units on EPC record in the building, where floor areas span 34–93 m². The building's EPC ratings span C to B, with this unit at the top.
Held since July 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 66 m² the property is well over the postcode median (49 m² across 14 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £209,000 is 29.8% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£227/sq ft) was about 29.1% below the postcode norm.
