39 Rosegarth Avenue is a four-bedroom semi-detached house in Aston, Sheffield, Sheffield (S26 2DB). It has a recorded floor area of 127 m² (around 1367 sq ft), construction records dating it to 1967-1975 and council tax band B. The latest certificate (August 2013) shows an E (score 44), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2011); the latest reading is one band lower. Between certificates, wall efficiency dropped from Good to Poor and roof efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from August 2013, so improvements made since then won't be reflected. Other recorded features include a self-contained annexe. Records show the property has been extended at some point in its history.

Untraded for 17 years, with the last transfer in July 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 127 m² the property is well over the postcode median (79 m² across 21 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 £269,000 sits 88.1% above the 2009 sale of £143,000. On a £-per-square-foot basis, the last sale (£105/sq ft) was about 28% below the postcode norm.
