About 61a
61a is a detached house in Isleworth (TW7 7NS). It has a recorded floor area of 50 m² (around 538 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (September 2021) shows a D (score 68), on the cusp of jumping into the C band. Earlier certificates rated it C (November 2008); the latest reading is one band lower.

The recommended improvements would lift it to B (score 88), a 2-band jump.
Held since November 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £419,000 sits 99.5% above the 2009 sale of £210,000. On a £-per-square-foot basis, the last sale (£390/sq ft) was about 18.7% above the typical sold price in the postcode. At 50 m² it sits well below the postcode median (102 m² across 22 EPCs), making it one of the more compact homes locally. One planning record on file: an extension refused in 2018.
