20 Ferversham Terrace, Ferryhill, DL17 0BW

20 Ferversham Terrace is a two-bedroom mid-terrace house in Ferryhill (DL17 0BW). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1930-1949 and council tax band A. The latest certificate (April 2015) shows an E (score 54), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2009); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Poor; 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 83), a 3-band jump. The latest certificate is from April 2015, so improvements made since then won't be reflected.

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. Today's modelled estimate of £103,000 sits 281.5% above the 2009 sale of £27,000. On a £-per-square-foot basis, the last sale (£30/sq ft) was about 37.9% below the postcode norm.
