11 Blenheim Crescent is a one-bedroom detached house in South Croydon (CR2 6BQ). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 1900-1929 and council tax band C. At 107 m² this is the 12th smallest of 14 units on EPC record in the building, where floor areas span 32–175 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (September 2009) shows a C (score 75), near the top of the C band. The rating has held steady at C across 3 certificates since January 2009. Between certificates, hot-water efficiency went from Good to Very Good, lighting went from Poor to Good and main heating went from Good to Very Good. The latest certificate is from September 2009, so improvements made since then won't be reflected.

Held since August 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 107 m² the property is well over the postcode median (59 m² across 13 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £281,000 sits 75.6% above the 2007 sale of £160,000. On a £-per-square-foot basis, the last sale (£139/sq ft) was about 47.7% below the postcode norm. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension, a loft conversion and subdivision, meaningful when judging how the property has evolved.
