20a is a detached house in Great Brickhill, Milton Keynes, Milton Keynes (MK17 9AR). It has a recorded floor area of 208 m² (around 2236 sq ft) and council tax band G. The latest certificate (November 2010) shows a C (score 80), near the top of the C band. The recommended improvements would push it to B (score 81). The latest certificate is from November 2010, so improvements made since then won't be reflected.
At 208 m² the property is well over the postcode median (113 m² across 14 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). Today's modelled estimate of £808,000 sits 61.6% above the 2011 sale of £499,999. On a £-per-square-foot basis, the last sale (£224/sq ft) was about 42.8% below the postcode norm. One planning record on file: a loft conversion approved in 2021. Past consents include a loft conversion, meaningful when judging how the property has evolved. Last sold in November 2011, so it's been off the market for around 15 years.
