About 44a
44a is a two-bedroom detached house in Isleworth (TW7 4BB). It has a recorded floor area of 53 m² (around 570 sq ft), construction records dating it to 1983-1990 and council tax band D. Tenure is freehold. The latest certificate (March 2018) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since October 2010. Between certificates, roof efficiency went from Average to Good. The recommended improvements would lift it to B (score 84), a 2-band jump. The home occupies a cul-de-sac position.
At 53 m² it sits well below the postcode median (100 m² across 15 EPCs), making it one of the more compact homes locally. One planning record on file: an extension approved in 2022. Past consents include an extension, a garage conversion and a porch, meaningful when judging how the property has evolved. Today's modelled estimate of £497,000 is 14.3% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£763/sq ft) was about 63% above the typical sold price in the postcode. Sold January 2022 for £435,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
