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. Today's modelled estimate of £418,000 sits 70.6% above the 2009 sale of £245,000. On a £-per-square-foot basis, the last sale (£406/sq ft) was about 31.3% above the typical sold price in the postcode. At 56 m² it sits well below the postcode median (86 m² across 7 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). 2 planning records sit against the property, 1 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
