It has a recorded floor area of 42 m² (around 452 sq ft), construction records dating it to 1930-1949 and council tax band E. The latest certificate (April 2024) shows a D (score 65), on the cusp of jumping into the C band. Earlier certificates rated it C (October 2010); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 69).

It hasn't traded since March 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £350,000 sits 191.7% above the 2007 sale of £120,000. At 42 m² it's 22.2% smaller than the typical home in the postcode (54 m² median across 35 EPCs). One historical planning record sits against the property in 2020.
