15a is a five-bedroom detached house in Great Horwood, Milton Keynes, Milton Keynes (MK17 0QE). It has a recorded floor area of 196 m² (around 2115 sq ft), construction records dating it to 1983-1990 and council tax band G. The latest certificate (July 2011) shows a D (score 67), on the cusp of jumping into the C band. Main heating runs on oil. The latest certificate is from July 2011, so improvements made since then won't be reflected. Other recorded features include outbuildings and attached land beyond the plot.
It hasn't traded since October 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 196 m² the property is well over the postcode median (107 m² across 21 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £763,000 sits 263.3% above the 1999 sale of £210,000. On a £-per-square-foot basis, the last sale (£99/sq ft) was about 63.5% below the postcode norm. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
