Get started66 Tristan Close is a three-bedroom mid-terrace house in Calshot, Southampton, Southampton (SO45 1BN). It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (October 2015) shows an E (score 40), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 82), a 3-band jump. The latest certificate is from October 2015, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.
At 96 m² the property is well over the postcode median (72 m² across 44 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. One planning record on file: an extension approved in 2003. Past consents include an extension, meaningful when judging how the property has evolved. Today's modelled estimate of £268,000 is 22.9% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£211/sq ft) was about 73.4% above the typical sold price in the postcode. Sold April 2021 for £218,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
