Held since April 2001 — that's 25 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 154 m² the property is well over the postcode median (102 m² across 17 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £538,000 sits 313.8% above the 2001 sale of £130,000. On a £-per-square-foot basis, the last sale (£78/sq ft) was about 77.5% below the postcode norm. One planning record on file: an extension approved in 2008. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved.
