Held since December 2008 — that's 17 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. Its energy rating outperforms most of the postcode (better than 79% of similar EPCs). On a £-per-square-foot basis, the last sale (£239/sq ft) was about 38.2% above the typical sold price in the postcode.
