About 3 Glendower
3 Glendower is an end-of-terrace house in Naphill, High Wycombe, High Wycombe (HP14 4QY). It has a recorded floor area of 127 m² (around 1367 sq ft), construction records dating it to 2007-2011 and council tax band B. The latest certificate (January 2024) shows a C (score 79), near the top of the C band. When first surveyed in October 2020 the rating was D, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good and lighting went from Very Poor to Very Good. The recommended improvements would push it to B (score 88).
It hasn't traded since August 2007, a hold of 19 years that's notably long for the area.

Today's modelled estimate of £535,000 sits 265.2% above the 2007 sale of £146,500. On a £-per-square-foot basis, the last sale (£107/sq ft) was about 74.2% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 127 m² it's 23.3% larger than the typical home in the postcode (103 m² median across 23 EPCs).
