Untraded for 18 years, with the last transfer in March 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 46 m² it sits well below the postcode median (81 m² across 15 EPCs), making it one of the more compact homes locally. Across 2005–2008, sale prices on this property compounded at 10.9% per year.

One historical planning record sits against the property in 2019.
