About Wye House
Wye House is a three-bedroom detached house in High Wycombe (HP11 1DJ). It has a recorded floor area of 119 m² (around 1281 sq ft), construction records dating it to 1930-1949 and council tax band E. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (August 2015) shows a D (score 55), a step below the typical UK home. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.
3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. At 119 m² it's 23.5% larger than the typical home in the postcode (96 m² median across 12 EPCs). Today's modelled estimate of £565,000 is 20.9% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£365/sq ft) was about 15.3% above the typical sold price in the postcode. Last changed hands 10 years ago, in February 2016.
