About 8 Berthwin Street
8 Berthwin Street is a four-bedroom mid-terrace house in Cardiff (CF11 9JH). It has a recorded floor area of 163 m² (around 1755 sq ft), construction records dating it to 1900-1929 and council tax band G. The latest certificate (November 2015) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 75). The latest certificate is from November 2015, so improvements made since then won't be reflected. Period features are noted in the property record.
Untraded for 19 years, with the last transfer in April 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2003–2007, sale prices on this property compounded at 11.6% per year. Today's modelled estimate of £582,000 sits 54% above the 2007 sale of £378,000. At 163 m² it's 15.1% larger than the typical home in the postcode (142 m² median across 12 EPCs). One historical planning record sits against the property in 2012.
