Held since January 2008 — that's 18 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. Today's modelled estimate of £571,000 sits 1869% above the 2008 sale of £29,000. On a £-per-square-foot basis, the last sale (£29/sq ft) was about 95% below the postcode norm. At 93 m² it's 29.2% larger than the typical home in the postcode (72 m² median across 37 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs).
