It hasn't traded since November 1996, a hold of 30 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £298,000 sits 250.6% above the 1996 sale of £85,000. On a £-per-square-foot basis, the last sale (£263/sq ft) was about 23.7% below the postcode norm. At 30 m² it sits well below the postcode median (126 m² across 29 EPCs), making it one of the more compact homes locally. One planning record on file: an extension approved in 2009. Past consents include an extension, meaningful when judging how the property has evolved.
