Held since November 1997 — that's 28 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. One planning application is currently pending a decision in 2026. At 168 m² the property is well over the postcode median (68 m² across 9 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £879,000 sits 506.2% above the 1997 sale of £145,000. On a £-per-square-foot basis, the last sale (£80/sq ft) was about 81.9% below the postcode norm.
