Chelsea House, 11, 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 45 m² (around 484 sq ft), construction records dating it to 2007 onwards and council tax band B. At 45 m² this is the 6th 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 bottom. The latest certificate (June 2014) shows a C (score 77), near the top of the C band. The latest certificate is from June 2014, so improvements made since then won't be reflected.
Untraded for 19 years, with the last transfer in October 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. It lags the bulk of the postcode on energy efficiency (less efficient than 72% of similar EPCs). Today's modelled estimate of £143,000 is 29.4% above the 2007 sale price.
