About 20 Pelican Street
20 Pelican Street is a three-bedroom mid-terrace house in Ystradgynlais, Swansea, Swansea (SA9 1LG). It has a recorded floor area of 106 m² (around 1143 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (February 2012) shows an F (score 32), near the bottom of the EPC scale. The latest certificate is from February 2012, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs). Across 2012–2017, sale prices on this property compounded at 24% per year. Today's modelled estimate of £196,000 is 20.6% above the 2017 sale price. On a £-per-square-foot basis, the last sale (£142/sq ft) was about 62.5% above the typical sold price in the postcode. Last sold in December 2017, so it's been off the market for around 8 years. One historical planning record sits against the property in 2017.
