On a £-per-square-foot basis, the last sale (£311/sq ft) was about 33.4% above the typical sold price in the postcode. Untraded for 19 years, with the last transfer in September 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
