It has a recorded floor area of 37 m² (around 398 sq ft), construction records dating it to 2003-2006 and council tax band C. At 37 m² this is the 3rd smallest of 34 units on EPC record in the building, where floor areas span 35–71 m². The building's EPC ratings span D to C, with this unit at the top. Other recorded features include a balcony and notable views. The latest certificate (June 2025) shows a C (score 80), near the top of the C band.

Today's modelled estimate of £104,000 is 13.3% below the 2007 sale of £119,995, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£301/sq ft) was about 29.7% above the typical sold price in the postcode. Untraded for 19 years, with the last transfer in September 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
