It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (April 2024) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since September 2009.
