About 25 Ocean Buildings
25 Ocean Buildings is a two-bedroom mid-terrace house in Cardiff (CF10 5AY). It has a recorded floor area of 69 m² (around 743 sq ft), construction records dating it to 2003-2006 and council tax band F. The latest certificate (January 2021) returns a B (score 84), comfortably above the UK average. Main heating runs on electricity. At 69 m² this is the 8th smallest of 28 units on EPC record in the building, where floor areas span 54–108 m². The building's EPC ratings span D to B, with this unit at the top. Other recorded features include a balcony.
Held since January 2007 — that's 20 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. Its energy rating outperforms most of the postcode (better than 70% of similar EPCs). Today's modelled estimate of £166,000 is 10.7% above the 2007 sale price.
