About 15 Mountain Road
15 Mountain Road is a four-bedroom semi-detached house in Craig-Cefn-Parc, Swansea, Swansea (SA6 5RH). It has a recorded floor area of 139 m² (around 1496 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (July 2012) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 86), a 3-band jump. The latest certificate is from July 2012, so improvements made since then won't be reflected. Other recorded features include notable views and a conservatory. Records show the property has been extended at some point in its history.
At 139 m² the property is well over the postcode median (104 m² across 13 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2007. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Across 1996–2021, sale prices on this property compounded at 9.1% per year. Today's modelled estimate of £325,000 is 16.1% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£187/sq ft) was about 35.3% above the typical sold price in the postcode. Most recent transfer: November 2021 at £280,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
