Held since September 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 52 m² it sits well below the postcode median (86 m² across 7 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. On a £-per-square-foot basis, the last sale (£286/sq ft) was about 146.2% above the typical sold price in the postcode.
