It hasn't traded since December 1999, a hold of 26 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 £312,000 sits 73.3% above the 1999 sale of £180,000. One planning record on file: tree works approved in 2017. Past consents include tree works, meaningful when judging how the property has evolved.
