Held since June 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.

On a £-per-square-foot basis, the last sale (£176/sq ft) was about 16.4% below the postcode norm. 5 bedrooms is on the larger side for this postcode, where 3 is the typical count.
