The latest certificate is from October 2010, so improvements made since then won't be reflected. Other recorded features include notable views.

Held since September 1996 — 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. Today's modelled estimate of £137,000 sits 408.3% above the 1996 sale of £26,950.
