Held since September 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 230 m² the property is well over the postcode median (45 m² across 25 EPCs), placing it in the larger end of the local stock. Across 1997–2009, sale prices on this property compounded at 11.1% per year. Today's modelled estimate of £1,699,000 sits 132.7% above the 2009 sale of £730,000. On a £-per-square-foot basis, the last sale (£295/sq ft) was about 27% above the typical sold price in the postcode. One planning record on file: a loft conversion approved in 2003. Past consents include a loft conversion, meaningful when judging how the property has evolved.
