About 17 Wellington Street
17 Wellington Street is a four-bedroom detached house in Tongwynlais, Cardiff, Cardiff (CF15 7LP). It has a recorded floor area of 118 m² (around 1270 sq ft), construction records dating it to 1930-1949 and council tax band E. The latest certificate (May 2014) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected. Other recorded features include a conservatory.
At 118 m² it's 24.9% larger than the typical home in the postcode (95 m² median across 16 EPCs). Today's modelled estimate of £410,000 is 19.7% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£270/sq ft) was about 36.7% above the typical sold price in the postcode. One planning record on file: an extension refused in 2000. Most recent transfer: June 2021 at £342,500. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
