About 17 Caswell Lane
17 Caswell Lane is a three-bedroom detached house in Portbury, Bristol, Bristol (BS20 7UF). It has a recorded floor area of 102 m² (around 1098 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (May 2013) shows an E (score 42), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from May 2013, so improvements made since then won't be reflected.
At 102 m² it's 20.9% smaller than the typical home in the postcode (129 m² median across 11 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 2002–2015, sale prices on this property compounded at 4.6% per year. Today's modelled estimate of £529,000 sits 53.3% above the 2015 sale of £345,000.
