Held since November 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 243 m² the property is well over the postcode median (63 m² across 26 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). Today's modelled estimate of £160,000 sits 113.3% above the 2009 sale of £75,000. On a £-per-square-foot basis, the last sale (£29/sq ft) was about 74.7% below the postcode norm. One historical planning record sits against the property in 2016.
