About 3 Castle Street
3 Castle Street is a four-bedroom mid-terrace house in Newport (NP20 2DF). It has a recorded floor area of 120 m² (around 1292 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (October 2015) shows an E (score 43), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 78), a 2-band jump. The latest certificate is from October 2015, so improvements made since then won't be reflected.
Untraded for 18 years, with the last transfer in July 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £153,000 sits 50% above the 2008 sale of £102,000. On a £-per-square-foot basis, the last sale (£79/sq ft) was about 17.8% below the postcode norm. At 120 m² it's 17.6% larger than the typical home in the postcode (102 m² median across 19 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 79% of similar EPCs).
