Held since March 1999 — that's 27 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 £350,000 sits 233.3% above the 1999 sale of £105,000. On a £-per-square-foot basis, the last sale (£184/sq ft) was about 56.4% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). One planning record on file: an extension refused in 2007.
