About 21 Cliff Road
21 Cliff Road is a semi-detached house in Southampton (SO15 1JN). It has a recorded floor area of 141 m² (around 1518 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (August 2013) shows a C (score 70). The recommended improvements would push it to B (score 83). The latest certificate is from August 2013, so improvements made since then won't be reflected.

At 141 m² the property is well over the postcode median (78 m² across 10 EPCs), placing it in the larger end of the local stock. Across 1999–2004, sale prices on this property compounded at 24.1% per year. Today's modelled estimate of £285,000 sits 71.4% above the 2004 sale of £166,250. On a £-per-square-foot basis, the last sale (£110/sq ft) was about 18% below the postcode norm. One planning record on file: an extension approved in 2015.
