About 21 Llwyn Mallt

21 Llwyn Mallt is a detached house in Tongwynlais, Cardiff, Cardiff (CF15 7HW). It has a recorded floor area of 111 m² (around 1195 sq ft), construction records dating it to 1983-1990 and council tax band F. The latest certificate (March 2014) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 82), a 3-band jump. The latest certificate is from March 2014, so improvements made since then won't be reflected.
