About 20 Robert Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
20 Robert Street is a three-bedroom mid-terrace house in Ely, Cardiff, Cardiff (CF5 5AA). It has a recorded floor area of 111 m² (around 1195 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (August 2019) shows a D (score 68), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since May 2009. Between certificates, window efficiency went from Poor to Average and lighting went from Average to Good; while roof efficiency dropped from Average to Very Poor. The recommended improvements would push it to C (score 80).
It hasn't traded since July 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £218,000 sits 74.4% above the 2009 sale of £125,000. 5 planning records sit against the property, 2 approved, 2 refused. Past consents include an extension and an annexe, meaningful when judging how the property has evolved.
