About 21 Grafton Street

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

21 Grafton Street is a four-bedroom mid-terrace house in Cambridge (CB1 1DS). It has a recorded floor area of 99 m² (around 1066 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (February 2014) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 79).
