Get started1 Cassiobury Avenue is a four-bedroom end-of-terrace house in Feltham (TW14 9JE). It has a recorded floor area of 139 m² (around 1495 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (September 2010) shows a C (score 71). The latest certificate is from September 2010, so improvements made since then won't be reflected. Other recorded features include a conservatory.
Held since January 2011 — that's 15 years off the open market, well above the local norm. At 139 m² the property is well over the postcode median (72 m² across 26 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £518,000 sits 66.6% above the 2011 sale of £311,000. On a £-per-square-foot basis, the last sale (£208/sq ft) was about 30.7% below the postcode norm. One planning record on file: an extension approved in 2024. Past consents include an extension and a porch, meaningful when judging how the property has evolved.
