Get startedMountain Ash is a detached house in King's Lynn (PE33 9JN). It has a recorded floor area of 204 m² (around 2196 sq ft) and construction records dating it to 1967-1975. The latest certificate (December 2015) shows a D (score 57), a step below the typical UK home. The recommended improvements would push it to C (score 69). Main heating runs on oil. The latest certificate is from December 2015, so improvements made since then won't be reflected.
It hasn't traded since April 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. At 204 m² the property is well over the postcode median (127 m² across 21 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £478,000 sits 703.4% above the 1997 sale of £59,500. On a £-per-square-foot basis, the last sale (£27/sq ft) was about 80.9% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved.
Mountain Ash's carbon output runs well above what efficient homes in the postcode produce.
