It has a recorded floor area of 158 m² (around 1701 sq ft), construction records dating it to 1991-1995 and council tax band B. The latest certificate (July 2015) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (September 2013); the latest reading is one band lower. Between certificates, lighting went from Average to Very Good; while roof efficiency dropped from Good to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 82), a 3-band jump. The latest certificate is from July 2015, so improvements made since then won't be reflected.

Held since April 2008 — that's 18 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. Sale prices here have outpaced Birmingham HPI: 9.4% per year against 0% for the wider region. Today's modelled estimate of £267,000 sits 60.8% above the 2008 sale of £166,000. On a £-per-square-foot basis, the last sale (£98/sq ft) was about 28.2% below the postcode norm. At 158 m² the property is well over the postcode median (69 m² across 13 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). One planning record on file: an extension approved in 2004. Past consents include an extension, meaningful when judging how the property has evolved.
