About 11 Blackett Close
11 Blackett Close is a four-bedroom detached house in Staines Upon Thames (TW18 3NW). It has a recorded floor area of 139 m² (around 1496 sq ft), construction records dating it to 1983-1990 and council tax band G. The property has an EV charger and underfloor heating on record, all of which lower running costs and tend to lift resale appeal. The home occupies a cul-de-sac position. The latest certificate (September 2025) shows a C (score 73).
Held since May 1996 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £754,000 sits 318.9% above the 1996 sale of £180,000. On a £-per-square-foot basis, the last sale (£120/sq ft) was about 64.7% below the postcode norm. One planning record on file: new windows refused in 2026.
