Held since October 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. At 43 m² it's 19.4% larger than the typical home in the postcode (36 m² median across 69 EPCs). Today's modelled estimate of £128,000 is 42.2% above the 2008 sale price.
