About 1 Ambleside Avenue
1 Ambleside Avenue is a five-bedroom semi-detached house in Beckenham (BR3 3RN). It has a recorded floor area of 137 m² (around 1473 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (August 2009) shows a D (score 55), a step below the typical UK home. The latest certificate is from August 2009, so improvements made since then won't be reflected.
It hasn't traded since November 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. At 137 m² the property is well over the postcode median (98 m² across 5 EPCs), placing it in the larger end of the local stock. 5 bedrooms is on the larger side for this postcode, where 4 is the typical count. Today's modelled estimate of £761,000 sits 97.7% above the 2009 sale of £385,000. On a £-per-square-foot basis, the last sale (£261/sq ft) was about 15.5% below the postcode norm. One historical planning record sits against the property in 2010.
