Held since December 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. On a £-per-square-foot basis, the last sale (£289/sq ft) was about 24.3% above the typical sold price in the postcode. At 37 m² it's 19.6% smaller than the typical home in the postcode (46 m² median across 67 EPCs).
