Held since July 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. At 76 m² it's 23.6% larger than the typical home in the postcode (62 m² median across 22 EPCs). On a £-per-square-foot basis, the last sale (£149/sq ft) was about 31% below the postcode norm.
