Held since December 1999 — that's 26 years off the open market, well above the local norm. At 180 m² the property is well over the postcode median (129 m² across 30 EPCs), placing it in the larger end of the local stock. Across 1997–1999, sale prices on this property compounded at 5% per year. Today's modelled estimate of £322,000 sits 373.5% above the 1999 sale of £68,000. On a £-per-square-foot basis, the last sale (£35/sq ft) was about 15.4% below the postcode norm. One planning record on file: an extension approved in 2017. Past consents include an extension, meaningful when judging how the property has evolved.
