It hasn't traded since November 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 75 m² it's 20.3% larger than the typical home in the postcode (63 m² median across 12 EPCs). Its energy rating outperforms most of the postcode (better than 75% of similar EPCs).
