Held since November 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 165 m² the property is well over the postcode median (110 m² across 15 EPCs), placing it in the larger end of the local stock. Across 1996–2009, sale prices on this property compounded at 8.8% per year. Today's modelled estimate of £859,000 sits 102.1% above the 2009 sale of £425,000. On a £-per-square-foot basis, the last sale (£239/sq ft) was about 40% 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.
