Chelsea House, 12, 599 Witan Gate, Milton Keynes, MK9 2BU
About Chelsea House
Chelsea House is a one-bedroom mid-terrace house in Milton Keynes (MK9 2BU). It has a recorded floor area of 50 m² (around 538 sq ft), construction records dating it to 2007-2011 and council tax band B. The latest certificate (September 2023) returns a B (score 82), comfortably above the UK average. When first surveyed in May 2013 the rating was C, the property has climbed 1 band since. Between certificates, lighting went from Average to Very Good. At 50 m² this is the 20th smallest of 48 units on EPC record in Chelsea House, where floor areas span 43–85 m². The building's EPC ratings span C to B, with this unit at the top.
It hasn't traded since October 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. Today's modelled estimate of £153,000 is 34.2% above the 2007 sale price.
