Breakwater House is a two-bedroom mid-terrace house in Cardiff (CF11 0JQ). 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 D (score 68), on the cusp of jumping into the C band. When first surveyed in August 2009 the rating was E, the property has climbed 1 band since. Between certificates, lighting went from Average to Good; while hot-water efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. Main heating runs on electricity. At 56 m² this is the 23rd smallest of 52 units on EPC record in Breakwater House, where floor areas span 35–100 m².

Today's modelled estimate of £168,000 is 28.5% below the 2007 sale of £235,000, 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 (£390/sq ft) was about 34% above the typical sold price in the postcode. Untraded for 19 years, with the last transfer in July 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
