Held since November 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. Today's modelled estimate of £114,000 sits 101.8% above the 2007 sale of £56,500. On a £-per-square-foot basis, the last sale (£87/sq ft) was about 24.3% above the typical sold price in the postcode. At 60 m² it sits well below the postcode median (160 m² across 34 EPCs), making it one of the more compact homes locally. One planning record on file: new windows approved in 2012. Past consents include new windows, meaningful when judging how the property has evolved.
