Held since April 2007 — that's 19 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 106 m² the property is well over the postcode median (68 m² across 18 EPCs), placing it in the larger end of the local stock. Across 2007–2007, sale prices on this property compounded at 34.3% per year. Today's modelled estimate of £393,000 sits 109% above the 2007 sale of £188,000. On a £-per-square-foot basis, the last sale (£165/sq ft) was about 32.7% below the postcode norm. One planning record on file: an extension approved in 2011. Past consents include an extension, meaningful when judging how the property has evolved.
