1 Chatsworth Avenue, Cambridge, CB4 3LT

1 Chatsworth Avenue is a two-bedroom detached house in Cambridge (CB4 3LT). It has a recorded floor area of 59 m² (around 631 sq ft), construction records dating it to 1967-1975 and council tax band B. At 59 m² this is the 20th smallest of 38 units on EPC record in the building, where floor areas span 45–82 m². The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (October 2009) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 79). The latest certificate is from October 2009, so improvements made since then won't be reflected.

It hasn't traded since July 2001, a hold of 25 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £274,000 sits 181% above the 2001 sale of £97,500. On a £-per-square-foot basis, the last sale (£154/sq ft) was about 43.4% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 70% of similar EPCs).
