Held since July 1996 — that's 30 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. Today's modelled estimate of £138,000 sits 638% above the 1996 sale of £18,700. On a £-per-square-foot basis, the last sale (£15/sq ft) was about 76% below the postcode norm. One planning record on file: an extension approved in 2009. Past consents include an extension, meaningful when judging how the property has evolved. At 115 m² it's 18.6% larger than the typical home in the postcode (97 m² median across 33 EPCs).
