18 Duncansby House, Ferry Court, Cardiff, CF11 0AT

18 Duncansby House is a two-bedroom mid-terrace house in Cardiff (CF11 0AT). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to 2003-2006 and council tax band E. The latest certificate (November 2019) shows a C (score 75), near the top of the C band. When first surveyed in July 2009 the rating was D, the property has climbed 1 band since. Between certificates, lighting went from Poor to Good; while hot-water efficiency dropped from Average to Very Poor. The recommended improvements would push it to B (score 86). Main heating runs on electricity. At 56 m² this is the 25th smallest of 65 units on EPC record in the building, where floor areas span 32–79 m². The building's EPC ratings span E to B across 65 units on file.

Today's modelled estimate of £167,000 is 21.2% below the 2008 sale of £212,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£352/sq ft) was about 35.6% above the typical sold price in the postcode. Untraded for 18 years, with the last transfer in February 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
