Held since June 1997 — that's 29 years off the open market, well above the local norm. 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 £327,000 sits 280.2% above the 1997 sale of £86,000. On a £-per-square-foot basis, the last sale (£131/sq ft) was about 28.4% below the postcode norm. At 61 m² it's 21.9% larger than the typical home in the postcode (50 m² median across 6 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).
