12a, Lancaster Way, East Winch, King's Lynn, PE32 1NY

12a is a four-bedroom detached house in King's Lynn (PE32 1NY). It has a recorded floor area of 86 m² (around 926 sq ft), construction records dating it to 1996-2002 and council tax band D. The latest certificate (July 2015) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in May 2013 the rating was E, the property has climbed 1 band since. Between certificates, lighting went from Average to Very Good and main heating went from Poor to Average; while roof efficiency dropped from Average to Poor and hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. Main heating runs on electricity. The latest certificate is from July 2015, so improvements made since then won't be reflected.

It hasn't traded since April 2006, a hold of 20 years that's notably long for the area. Across 1996–2006, sale prices on this property compounded at 11% per year. Today's modelled estimate of £325,000 sits 65% above the 2006 sale of £197,000. On a £-per-square-foot basis, the last sale (£213/sq ft) was about 43.6% above the typical sold price in the postcode. One planning record on file: an extension refused in 2007.
