It hasn't traded since September 2003, a hold of 23 years that's notably long for the area. At 108 m² the property is well over the postcode median (69 m² across 7 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). Today's modelled estimate of £325,000 sits 97% above the 2003 sale of £165,000. On a £-per-square-foot basis, the last sale (£142/sq ft) was about 55.7% below the postcode norm. One planning record on file: an extension approved in 2011. Past consents include an extension, meaningful when judging how the property has evolved.
