Flat 1, 11 Duncan Road, Richmond, TW9 2JD
About Flat 1
Flat 1 is a detached house in Richmond (TW9 2JD). It has a recorded floor area of 43 m² (around 464 sq ft), construction records dating it to 1900-1929 and council tax band C. At 43 m² this is the smallest unit on EPC record across the building (43–48 m²). The latest certificate (June 2011) shows a D (score 62), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since January 2009. Between certificates, lighting went from Good to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The latest certificate is from June 2011, so improvements made since then won't be reflected.
At 43 m² it sits well below the postcode median (97 m² across 31 EPCs), making it one of the more compact homes locally.
