Held since November 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 55 m² it's 21.4% smaller than the typical home in the postcode (70 m² median across 11 EPCs). Its energy rating outperforms most of the postcode (better than 82% of similar EPCs).
