About 21 Barrow Avenue
21 Barrow Avenue is a three-bedroom semi-detached house in Carshalton (SM5 4NY). It has a recorded floor area of 119 m² (around 1281 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (May 2013) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from May 2013, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.
Today's modelled estimate of £756,000 sits 71.4% above the 2013 sale of £441,000. On a £-per-square-foot basis, the last sale (£344/sq ft) was about 27.1% above the typical sold price in the postcode. One planning record on file: an extension approved in 2022. Past consents include an extension and a garage conversion, meaningful when judging how the property has evolved. Last sold in September 2013, so it's been off the market for around 13 years. At 119 m² it's 16% smaller than the typical home in the postcode (142 m² median across 14 EPCs).
