Chelsea House, 57, 599 Witan Gate, Milton Keynes, MK9 2BS

Chelsea House is a two-bedroom end-of-terrace house in Milton Keynes (MK9 2BS). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 2007 onwards and council tax band C. The latest certificate (June 2019) returns a B (score 82), comfortably above the UK average. The rating has held steady at B across 2 certificates since February 2009. Between certificates, wall efficiency went from Good to Very Good; while lighting dropped from Very Good to Average. At 77 m² this is the 44th smallest of 47 units on EPC record in Chelsea House, where floor areas span 40–77 m². The building's EPC ratings span C to B, with this unit at the top.

It hasn't traded since January 2008, 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. At 77 m² the property is well over the postcode median (50 m² across 46 EPCs), placing it in the larger end of the local stock.
