About 1 Clayton Road
1 Clayton Road is a six-bedroom end-of-terrace house in Isleworth (TW7 6LE). It has a recorded floor area of 123 m² (around 1324 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (April 2016) shows a C (score 69), just inside the C band. When first surveyed in March 2014 the rating was E, the property has climbed 2 bands since. Between certificates, window efficiency went from Average to Good, hot-water efficiency went from Poor to Good and lighting went from Good to Very Good; while roof efficiency dropped from Poor to Very Poor. The recommended improvements would push it to B (score 85). The latest certificate is from April 2016, so improvements made since then won't be reflected.
At 123 m² the property is well over the postcode median (92 m² across 8 EPCs), placing it in the larger end of the local stock. 6 bedrooms is on the larger side for this postcode, where 3 is the typical count. Today's modelled estimate of £758,000 sits 123.6% above the 2014 sale of £339,000. On a £-per-square-foot basis, the last sale (£256/sq ft) was about 35% below the postcode norm. 4 planning records sit against the property, 1 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved. Last sold in March 2014, so it's been off the market for around 12 years.
