About 12 Cornwall Grove
12 Cornwall Grove is a three-bedroom mid-terrace house in Hounslow, London, London (W4 2LB). It has a recorded floor area of 147 m² (around 1582 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (December 2025) shows a D (score 59), a step below the typical UK home. The recommended improvements would push it to C (score 77). This certificate was lodged in the last six months, so the rating reflects current condition.
It hasn't traded since February 1998, a hold of 28 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 147 m² the property is well over the postcode median (72 m² across 49 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £1,228,000 sits 401.2% above the 1998 sale of £245,000. On a £-per-square-foot basis, the last sale (£155/sq ft) was about 59% below the postcode norm. One planning record on file: an extension approved in 2023. Past consents include an extension, meaningful when judging how the property has evolved.
