About 1b
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
1b is a three-bedroom semi-detached house in Portsmouth (PO6 2JT). It has a recorded floor area of 80 m² (around 861 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (March 2017) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 81), a 3-band jump. Main heating runs on electricity.
Held since October 1995 — that's 31 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 £284,000 sits 373.4% above the 1995 sale of £59,995. On a £-per-square-foot basis, the last sale (£70/sq ft) was about 75% below the postcode norm. At 80 m² it's 15.8% smaller than the typical home in the postcode (95 m² median across 17 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
