309a, Richmond Road, Kingston Upon Thames, KT2 5QU

309a is a two-bedroom mid-terrace house in Kingston Upon Thames (KT2 5QU). It has a recorded floor area of 45 m² (around 483 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (August 2010) shows a D (score 62), on the cusp of jumping into the C band. The latest certificate is from August 2010, so improvements made since then won't be reflected. Other recorded features include a basement.

It hasn't traded since September 2007, a hold of 19 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. Across 1999–2007, sale prices on this property compounded at 10.7% per year. Today's modelled estimate of £385,000 sits 87.8% above the 2007 sale of £205,000. On a £-per-square-foot basis, the last sale (£425/sq ft) was about 19.6% above the typical sold price in the postcode. At 45 m² it sits well below the postcode median (77 m² across 12 EPCs), making it one of the more compact homes locally.
