It hasn't traded since December 2008, a hold of 17 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £264,000 sits 60% above the 2008 sale of £165,000. At 57 m² it's 22.6% larger than the typical home in the postcode (47 m² median across 34 EPCs).
