It hasn't traded since October 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 194 m² the property is well over the postcode median (114 m² across 13 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £859,000 sits 114.8% above the 2009 sale of £400,000. On a £-per-square-foot basis, the last sale (£192/sq ft) was about 53.9% below the postcode norm. 3 planning records sit against the property, 2 approved, 1 refused.
