Held since February 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. Today's modelled estimate of £294,000 sits 317% above the 2001 sale of £70,500. On a £-per-square-foot basis, the last sale (£65/sq ft) was about 34.5% below the postcode norm. One planning record on file: an extension approved in 2009.
