About 30 Balaclava Street
30 Balaclava Street is an end-of-terrace house in St. Thomas, Swansea, Swansea (SA1 8BR). It has a recorded floor area of 85 m² (around 915 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (March 2015) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 79), a 2-band jump. The latest certificate is from March 2015, so improvements made since then won't be reflected.
Held since March 1996 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £140,000 sits 460% above the 1996 sale of £25,000. On a £-per-square-foot basis, the last sale (£27/sq ft) was about 65.5% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs).
