27a is a detached house in Birmingham (B30 1JB). It has a recorded floor area of 89 m² (around 956 sq ft) and construction records dating it to before 1900. The latest certificate (November 2008) shows an F (score 27), near the bottom of the EPC scale. When first surveyed in November 2008 the rating was G, the property has climbed 1 band since. The recommended improvements would lift it to D (score 58), a 2-band jump. Main heating runs on electricity. The latest certificate is from November 2008, so improvements made since then won't be reflected. At 89 m² this is the 19th smallest of 23 units on EPC record in the building, where floor areas span 19–102 m². The building's EPC ratings span F to C, with this unit at the bottom. On EPC score it ranks last in the building (27 versus a best of 78).

It hasn't traded since May 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 89 m² the property is well over the postcode median (38 m² across 22 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £179,000 is 32.6% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£141/sq ft) was about 35.8% below the postcode norm.
