It has a recorded floor area of 185 m² (around 1991 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (August 2022) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 79), a 2-band jump.
