About 17 Bryn Rhosyn
17 Bryn Rhosyn is a three-bedroom detached house in Radyr, Cardiff, Cardiff (CF15 8RN). It has a recorded floor area of 73 m² (around 787 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (May 2010) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 71). The latest certificate is from May 2010, so improvements made since then won't be reflected.
Today's modelled estimate of £336,000 sits 71.4% above the 2014 sale of £196,000. On a £-per-square-foot basis, the last sale (£249/sq ft) was about 16.8% above the typical sold price in the postcode. One planning record on file: an extension approved in 2015. Past consents include an extension, a porch and a conservatory, meaningful when judging how the property has evolved. Last sold in October 2014, so it's been off the market for around 12 years.
