About 3 Bryn Rhosyn
3 Bryn Rhosyn is a three-bedroom semi-detached house in Radyr, Cardiff, Cardiff (CF15 8RN). It has a recorded floor area of 100 m² (around 1076 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (June 2012) shows a D (score 58), a step below the typical UK home. The recommended improvements would lift it to B (score 81), a 2-band jump.
