Held since May 1998 — 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. At 148 m² the property is well over the postcode median (101 m² across 12 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £134,000 sits 332.3% above the 1998 sale of £31,000. On a £-per-square-foot basis, the last sale (£19/sq ft) was about 69.5% below the postcode norm. One planning record on file: a loft conversion approved in 2004. Past consents include a loft conversion, meaningful when judging how the property has evolved.
