Held since February 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 129 m² the property is well over the postcode median (60 m² across 18 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs). Across 2005–2009, sale prices on this property compounded at 4.2% per year. Today's modelled estimate of £1,658,000 sits 84.2% above the 2009 sale of £900,000. On a £-per-square-foot basis, the last sale (£648/sq ft) was about 23.7% below the postcode norm.
