Untraded for 19 years, with the last transfer in March 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1997–2007, sale prices on this property compounded at 9.6% per year. Today's modelled estimate of £330,000 sits 79.3% above the 2007 sale of £184,000. At 52 m² it sits well below the postcode median (98 m² across 21 EPCs), making it one of the more compact homes locally. One planning record on file: an extension approved in 2017. Past consents include an extension, a conservatory and partial demolition, meaningful when judging how the property has evolved.
