About 11 Byron Road
11 Byron Road is a four-bedroom semi-detached house in Aylesbury (HP21 7LU). It has a recorded floor area of 145 m² (around 1563 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (February 2009) shows a D (score 59), a step below the typical UK home. The latest certificate is from February 2009, so improvements made since then won't be reflected.
It hasn't traded since March 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 145 m² the property is well over the postcode median (96 m² across 12 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £472,000 sits 90.3% above the 2009 sale of £248,000. On a £-per-square-foot basis, the last sale (£159/sq ft) was about 25.3% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a garage conversion, meaningful when judging how the property has evolved.
