Held since December 2008 — that's 17 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 30 m² it sits well below the postcode median (99 m² across 30 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 73% of similar EPCs). Across 1999–2008, sale prices on this property compounded at 8.2% per year. Today's modelled estimate of £462,000 is 44.4% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£991/sq ft) was about 204.1% above the typical sold price in the postcode. One planning record on file: an extension refused in 2003.
