Get started21 Margaretta Terrace is a mid-terrace house in Kensington And Chelsea, London, London (SW3 5NU). It has a recorded floor area of 174 m² (around 1873 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (May 2015) shows a D (score 58), a step below the typical UK home. The recommended improvements would push it to C (score 76). The latest certificate is from May 2015, so improvements made since then won't be reflected.
It hasn't traded since September 1998, a hold of 28 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £3,923,000 sits 416.2% above the 1998 sale of £760,000. On a £-per-square-foot basis, the last sale (£406/sq ft) was about 72.4% below the postcode norm. 5 planning records sit against the property, 2 approved, 2 refused.
