Get startedFlat 4 is a two-bedroom mid-terrace house in London (SW1X 0JU). It has a recorded floor area of 98 m² (around 1055 sq ft), construction records dating it to before 1900 and council tax band G. At 98 m² this is the 2nd smallest of 4 units on EPC record in the building, where floor areas span 96–209 m². The building's EPC ratings span D to C, with this unit at the top. The latest certificate (July 2020) shows a C (score 75), near the top of the C band. The rating has held steady at C across 3 certificates since December 2008. Between certificates, lighting went from Very Poor to Very Good; while window efficiency dropped from Poor to Very Poor. The recommended improvements would push it to B (score 84).
4 planning records sit against the property, 3 approved, 0 refused. The record references listed-building consent, which constrain future alterations. At 98 m² it sits well below the postcode median (146 m² across 14 EPCs), making it one of the more compact homes locally. On a £-per-square-foot basis, the last sale (£2,180/sq ft) was about 321.8% above the typical sold price in the postcode. Last sale on file: £2,300,000 in July 2022. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
