About 18a
18a is a one-bedroom end-of-terrace house in St. Thomas, Swansea, Swansea (SA1 8HH). It has a recorded floor area of 43 m² (around 463 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (May 2012) shows an E (score 41), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 84), a 3-band jump. The latest certificate is from May 2012, so improvements made since then won't be reflected.
Today's modelled estimate of £112,000 sits 77.8% above the 2016 sale of £63,000. On a £-per-square-foot basis, the last sale (£136/sq ft) was about 50.5% above the typical sold price in the postcode. At 43 m² it sits well below the postcode median (85 m² across 22 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs). One planning record on file: an extension approved in 2016. Past consents include an extension, meaningful when judging how the property has evolved. Last sold in May 2016, so it's been off the market for around 10 years.
