1 Devon Court is a one-bedroom end-of-terrace house in St Albans (AL1 1PP). It has a recorded floor area of 43 m² (around 463 sq ft), construction records dating it to 1950-1966 and council tax band C. At 43 m² this is the 3rd smallest of 15 units on EPC record in the building, where floor areas span 37–51 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (August 2012) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it C (March 2011); the latest reading is 2 bands lower. Between certificates, lighting went from Very Poor to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 73), a 2-band jump. Main heating runs on electricity. The latest certificate is from August 2012, so improvements made since then won't be reflected.

It hasn't traded since April 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. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £256,000 sits 169.6% above the 2001 sale of £94,950. On a £-per-square-foot basis, the last sale (£205/sq ft) was about 33.4% below the postcode norm.
