5 Cornish Close is a one-bedroom end-of-terrace house in Cardiff (CF11 7BR). It has a recorded floor area of 30 m² (around 323 sq ft), construction records dating it to 1976-1982 and council tax band B. Tenure is freehold. At 30 m² this is the smallest unit on EPC record across the building (30–43 m²). The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (40 versus a best of 76). The latest certificate (July 2012) shows an E (score 40), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 79), a 2-band jump. Main heating runs on electricity. The latest certificate is from July 2012, so improvements made since then won't be reflected.

Held since July 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 30 m² it's 21.1% smaller than the typical home in the postcode (38 m² median across 17 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs). Today's modelled estimate of £119,000 is 48.8% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£248/sq ft) was about 48.8% above the typical sold price in the postcode.
