Held since September 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 67 m² it's 15.2% smaller than the typical home in the postcode (79 m² median across 10 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 70% of similar EPCs).
