Untraded for 17 years, with the last transfer in November 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 227 m² the property is well over the postcode median (134 m² across 10 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £948,000 sits 64.9% above the 2009 sale of £575,000. On a £-per-square-foot basis, the last sale (£235/sq ft) was about 34.9% below the postcode norm. 3 planning records sit against the property, 2 approved, 1 refused.
