Flat 5, 86 Onslow Gardens, London, SW7 3BS

Flat 5 is a mid-terrace house in London (SW7 3BS). It has a recorded floor area of 61 m² (around 657 sq ft), construction records dating it to 1900-1929 and council tax band G. At 61 m² this is the 3rd smallest of 6 units on EPC record in the building, where floor areas span 38–74 m². The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (67 versus a best of 76). The latest certificate (September 2014) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from September 2014, so improvements made since then won't be reflected.

Untraded for 19 years, with the last transfer in January 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £1,234,000 is 45.2% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£1,295/sq ft) was about 66% above the typical sold price in the postcode. One historical planning record sits against the property in 2007.
