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

24 Duncansby House is a two-bedroom mid-terrace house in Cardiff (CF11 0AT). It has a recorded floor area of 41 m² (around 441 sq ft), construction records dating it to 2007 onwards and council tax band D. The latest certificate (August 2019) returns a high B (score 86), putting the home a stone's throw from an A rating. When first surveyed in January 2009 the rating was D, the property has climbed 2 bands since. Between certificates, window efficiency went from Average to Good and lighting went from Poor to Very Good. Main heating runs on electricity. At 41 m² this is the 8th 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, with this unit at the top.

Today's modelled estimate of £129,000 is 12.8% below the 2008 sale of £148,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£335/sq ft) was about 29.3% above the typical sold price in the postcode. It hasn't traded since January 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 41 m² it sits well below the postcode median (60 m² across 64 EPCs), making it one of the more compact homes locally.
