About 1 Castle Road
1 Castle Road is a two-bedroom end-of-terrace house in Tongwynlais, Cardiff, Cardiff (CF15 7JQ). It has a recorded floor area of 60 m² (around 646 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (January 2020) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 83), a 3-band jump.
At 60 m² it sits well below the postcode median (103 m² across 24 EPCs), making it one of the more compact homes locally.
