Get started28 Mallord Street is a six-bedroom detached house in Kensington And Chelsea, London, London (SW3 6DU). It has a recorded floor area of 424 m² (around 4564 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (May 2016) shows a C (score 77), near the top of the C band. When first surveyed in April 2016 the rating was D, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Very Good, roof efficiency went from Very Poor to Good and window efficiency went from Very Poor to Average. The latest certificate is from May 2016, so improvements made since then won't be reflected.
It hasn't traded since January 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. On energy efficiency it sits in the top 10% of properties in this postcode. Today's modelled estimate of £12,928,000 sits 138.3% above the 2009 sale of £5,425,000. On a £-per-square-foot basis, the last sale (£1,189/sq ft) was about 38.7% above the typical sold price in the postcode. 10 planning records sit against the property, 6 approved, 3 refused. The record references listed-building consent, which constrain future alterations.
28 Mallord Street ranks among the most efficient homes in the postcode for energy use.
