Get startedFlat 4 is a mid-terrace house in Kensington And Chelsea, London, London (SW1X 0DE). It has a recorded floor area of 68 m² (around 729 sq ft), construction records dating it to before 1900 and council tax band H. At 68 m² this is the smallest unit on EPC record across the building (68–127 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 (60 versus a best of 71). The latest certificate (January 2009) shows a D (score 60), on the cusp of jumping into the C band. The latest certificate is from January 2009, so improvements made since then won't be reflected.
Held since February 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. Sale prices here have outpaced London HPI: 11.4% per year against 0% for the wider region. Today's modelled estimate of £1,050,000 sits 59.1% above the 2007 sale of £660,000. On a £-per-square-foot basis, the last sale (£906/sq ft) was about 60.4% above the typical sold price in the postcode. 10 planning records sit against the property, 9 approved, 1 refused. Past consents include subdivision, meaningful when judging how the property has evolved. The record references listed-building consent, which constrain future alterations. At 68 m² it sits well below the postcode median (125 m² across 34 EPCs), making it one of the more compact homes locally.
