Held since August 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. At 130 m² it sits well below the postcode median (214 m² across 7 EPCs), making it one of the more compact homes locally. Across 1998–2007, sale prices on this property compounded at 16.3% per year. Today's modelled estimate of £1,155,000 is 40% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£588/sq ft) was about 92.4% above the typical sold price in the postcode.
