Castle House is a four-bedroom detached house in King's Lynn (PE32 1SF). It has a recorded floor area of 92 m² (around 993 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (October 2011) shows an F (score 38), near the bottom of the EPC scale. Earlier certificates rated it E (February 2009); the latest reading is one band lower. Between certificates, window efficiency went from Very Poor to Good and lighting went from Average to Good; while roof efficiency dropped from Average to Very Poor. The recommended improvements would push it to E (score 49). Main heating runs on oil. The latest certificate is from October 2011, so improvements made since then won't be reflected. Period features are noted in the property record.
Untraded for 30 years, with the last transfer in July 1996. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £399,000 sits 380.7% above the 1996 sale of £83,000. On a £-per-square-foot basis, the last sale (£84/sq ft) was about 47.5% below the postcode norm. At 92 m² it's 19.7% smaller than the typical home in the postcode (115 m² median across 14 EPCs).
