22 Alston Road, Barnet, EN5 4ET

22 Alston Road is a semi-detached house in Barnet (EN5 4ET). It has a recorded floor area of 37 m² (around 397 sq ft), construction records dating it to 1930-1949 and council tax band E. The latest certificate (March 2012) shows a D (score 60), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since May 2011. Between certificates, wall efficiency went from Very Poor to Poor. The latest certificate is from March 2012, so improvements made since then won't be reflected. At 37 m² this is the 2nd smallest of 16 units on EPC record in the building, where floor areas span 22–142 m². The building's EPC ratings span E to B across 16 units on file.

It hasn't traded since July 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 37 m² it sits well below the postcode median (71 m² across 15 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £437,000 is 21.4% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£906/sq ft) was about 156.8% above the typical sold price in the postcode.
