11a, Buckingham Way, Flackwell Heath, High Wycombe, HP10 9EH

11a is a semi-detached house in Flackwell Heath, High Wycombe, High Wycombe (HP10 9EH). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (October 2014) shows an E (score 47), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 88), a 3-band jump. The latest certificate is from October 2014, so improvements made since then won't be reflected.

It hasn't traded since July 1997, a hold of 29 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. Today's modelled estimate of £300,000 sits 266.1% above the 1997 sale of £81,950. On a £-per-square-foot basis, the last sale (£190/sq ft) was about 34% below the postcode norm. At 40 m² it sits well below the postcode median (93 m² across 31 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs). One planning record on file: an extension approved in 2001. Past consents include an extension, meaningful when judging how the property has evolved.
