About 20a
20a is a two-bedroom mid-terrace house in Farnborough (GU14 8TJ). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (October 2013) shows a C (score 72). The rating has held steady at C across 3 certificates since July 2012. Between certificates, wall efficiency went from Poor to Good; while roof efficiency dropped from Good to Average and window efficiency dropped from Good to Average. The recommended improvements would push it to B (score 87). The latest certificate is from October 2013, so improvements made since then won't be reflected.
It hasn't traded since June 2006, a hold of 20 years that's notably long for the area. Today's modelled estimate of £301,000 sits 68.2% above the 2006 sale of £179,000. On a £-per-square-foot basis, the last sale (£213/sq ft) was about 16.2% above the typical sold price in the postcode. One planning record on file: an extension approved in 2004.
