Held since November 1995 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 135 m² the property is well over the postcode median (75 m² across 15 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 80% of similar EPCs). Today's modelled estimate of £577,000 sits 541.1% above the 1995 sale of £90,000. On a £-per-square-foot basis, the last sale (£62/sq ft) was about 80.6% below the postcode norm. One planning record on file: a loft conversion approved in 2010. Past consents include a loft conversion and subdivision, meaningful when judging how the property has evolved.
