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 197 m² the property is well over the postcode median (115 m² across 13 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £1,161,000 sits 111.1% above the 2009 sale of £550,000. On a £-per-square-foot basis, the last sale (£259/sq ft) was about 22.6% below the postcode norm. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
