Across 1999–2022, sale prices on this property compounded at 6% per year. Today's modelled estimate of £930,000 is 14.7% below the 2022 sale of £1,090,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£1,250/sq ft) was about 39.8% above the typical sold price in the postcode. One historical planning record sits against the property in 2010. The record references listed-building consent, which constrain future alterations. Most recent transfer: December 2022 at £1,090,000.
