About 78 High Street
78 High Street is a four-bedroom detached house in Ammanford (SA18 2NB). It has a recorded floor area of 180 m² (around 1936 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (January 2012) shows an E (score 45), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 58). The latest certificate is from January 2012, so improvements made since then won't be reflected.
At 180 m² the property is well over the postcode median (102 m² across 29 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 72% of similar EPCs). Across 1995–2021, sale prices on this property compounded at 4.8% per year. Today's modelled estimate of £440,000 is 16.4% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£195/sq ft) was about 88.6% above the typical sold price in the postcode. Sold August 2021 for £378,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2015.
