Held since March 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. One planning record on file: subdivision approved in 2008. Past consents include subdivision, meaningful when judging how the property has evolved. Today's modelled estimate of £493,000 is 29.7% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£642/sq ft) was about 144.4% above the typical sold price in the postcode. At 55 m² it's 20.3% smaller than the typical home in the postcode (69 m² median across 23 EPCs).
