About 34 Lady Mary Road
34 Lady Mary Road is a four-bedroom detached house in Cardiff (CF23 5NT). It has a recorded floor area of 157 m² (around 1695 sq ft), construction records dating it to 1930-1949 and council tax band H. The latest certificate (March 2010) shows an E (score 48), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 69), a 2-band jump. The latest certificate is from March 2010, so improvements made since then won't be reflected. Period features are noted in the property record.
It hasn't traded since November 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £612,000 sits 178.2% above the 1999 sale of £220,000. On a £-per-square-foot basis, the last sale (£130/sq ft) was about 50.8% below the postcode norm.
