Held since September 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.

On a £-per-square-foot basis, the last sale (£162/sq ft) was about 52.3% above the typical sold price in the postcode. One historical planning record sits against the property in 2007.
