It has a recorded floor area of 240 m² (around 2583 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (February 2016) shows a D (score 59), a step below the typical UK home. The recommended improvements would push it to C (score 71). Main heating runs on oil.

Records show the property has been extended at some point in its history.

Held since June 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 240 m² the property is well over the postcode median (100 m² across 17 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £804,000 sits 60.8% above the 2007 sale of £500,000. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
