Held since September 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 127 m² the property is well over the postcode median (78 m² across 11 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs). 6 planning records sit against the property, 5 approved, 1 refused. Past consents include tree works, meaningful when judging how the property has evolved. Across 1995–2007, sale prices on this property compounded at 10.8% per year. Today's modelled estimate of £446,000 is 23.2% above the 2007 sale price.
