About 1 2
1 2 is an end-of-terrace house in Southampton (SO14 3DR). It has a recorded floor area of 34 m² (around 366 sq ft) and construction records dating it to before 1900. The latest certificate (August 2016) shows an E (score 40), well below the UK norm with real room to improve. When first surveyed in May 2009 the rating was F, the property has climbed 1 band since. Between certificates, lighting went from Average to Very Good and main heating went from Poor to Average; while window efficiency dropped from Good to Average. The recommended improvements would push it to D (score 68). Main heating runs on electricity. The latest certificate is from August 2016, so improvements made since then won't be reflected. At 34 m² this is the 5th smallest of 7 units on EPC record in 1 2, where floor areas span 24–57 m². The building's EPC ratings span E to D, with this unit at the bottom.
At 34 m² it sits well below the postcode median (57 m² across 25 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
