It hasn't traded since November 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £336,000 sits 68% above the 2008 sale of £200,000. On a £-per-square-foot basis, the last sale (£154/sq ft) was about 51% above the typical sold price in the postcode. 3 planning records sit against the property, 2 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 121 m² it's 23.5% larger than the typical home in the postcode (98 m² median across 15 EPCs). 7 bedrooms is on the larger side for this postcode, where 4 is the typical count.
