30 Duncansby House is a two-bedroom mid-terrace house in Cardiff (CF11 0AT). It has a recorded floor area of 61 m² (around 657 sq ft), construction records dating it to 2007 onwards and council tax band E. The latest certificate (January 2020) shows a C (score 77), near the top of the C band. The rating has held steady at C across 2 certificates since February 2010. Between certificates, lighting went from Average to Very Good; while hot-water efficiency dropped from Average to Very Poor. The recommended improvements would push it to B (score 87). Main heating runs on electricity. At 61 m² this is the 35th smallest of 65 units on EPC record in the building, where floor areas span 32–79 m².

Today's modelled estimate of £179,000 is 16.4% below the 2008 sale of £214,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£326/sq ft) was about 25.7% above the typical sold price in the postcode. Held since February 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
