Held since February 2008 — that's 18 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 57 m² it sits well below the postcode median (104 m² across 29 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 72% of similar EPCs). On a £-per-square-foot basis, the last sale (£216/sq ft) was about 110.1% above the typical sold price in the postcode.
