Get started43 William Smith Close is a one-bedroom detached house in Cambridge (CB1 3QE). It has a recorded floor area of 30 m² (around 323 sq ft), construction records dating it to 1983-1990 and council tax band A. The latest certificate (September 2018) shows a D (score 67), on the cusp of jumping into the C band. Earlier certificates rated it C (April 2009); the latest reading is one band lower. Between certificates, roof efficiency went from Average to Good, window efficiency went from Poor to Average and lighting went from Average to Good; while hot-water efficiency dropped from Average to Poor and main heating dropped from Poor to Very Poor. The recommended improvements would push it to C (score 77). Main heating runs on electricity. At 30 m² this is the 5th smallest of 37 units on EPC record in the building, where floor areas span 28–51 m². The building's EPC ratings span E to B across 37 units on file.
It hasn't traded since August 1996, a hold of 30 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 £186,000 sits 481.3% above the 1996 sale of £32,000. On a £-per-square-foot basis, the last sale (£99/sq ft) was about 56.7% below the postcode norm. At 30 m² it sits well below the postcode median (43 m² across 36 EPCs), making it one of the more compact homes locally.
43 William Smith Close's modelled value sits at over four times its earliest registered sale price (1996).
