About 27 Bronwydd Avenue
27 Bronwydd Avenue is a five-bedroom detached house in Cardiff (CF23 5JQ). It has a recorded floor area of 302 m² (around 3251 sq ft) and construction records dating it to 2003-2006. The latest certificate (January 2025) returns a B (score 81), comfortably above the UK average. When first surveyed in May 2009 the rating was F, the property has climbed 4 bands since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Average to Very Good and window efficiency went from Average to Good.
It hasn't traded since December 2009, a hold of 16 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 302 m² the property is well over the postcode median (129 m² across 6 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £799,000 sits 90.2% above the 2009 sale of £420,000. On a £-per-square-foot basis, the last sale (£129/sq ft) was about 56% below the postcode norm. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
