Get startedFlat 3 is a property in Kensington And Chelsea, London, London (SW1X 0DG). It has a recorded floor area of 31 m² (around 329 sq ft), construction records dating it to before 1900 and council tax band G. At 31 m² this is the smallest unit on EPC record across the building (31–103 m²). The building's EPC ratings span E to C across 6 units on file. The latest certificate (December 2011) shows a D (score 56), a step below the typical UK home. The latest certificate is from December 2011, so improvements made since then won't be reflected.
Today's modelled estimate of £1,434,000 is 24.6% below the 2007 sale of £1,901,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£5,775/sq ft) was about 470.6% above the typical sold price in the postcode. It hasn't traded since May 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 31 m² it sits well below the postcode median (95 m² across 30 EPCs), making it one of the more compact homes locally. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
