Held since February 1997 — that's 29 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 £156,000 sits 1460% above the 1997 sale of £10,000. On a £-per-square-foot basis, the last sale (£66/sq ft) was about 67.3% below the postcode norm. At 14 m² it sits well below the postcode median (56 m² across 42 EPCs), making it one of the more compact homes locally. One historical planning record sits against the property in 2010.
