Held since August 2007 — that's 19 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 (£301/sq ft) was about 55.5% above the typical sold price in the postcode. At 36 m² it's 20% smaller than the typical home in the postcode (45 m² median across 59 EPCs).
