About 15 Blackthorn Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
15 Blackthorn Close is a four-bedroom semi-detached house in St Albans (AL4 9RP). It has a recorded floor area of 146 m² (around 1572 sq ft), construction records dating it to 1950-1966 and council tax band F. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The home occupies a cul-de-sac position. The latest certificate (April 2017) shows a C (score 70).
Untraded for 17 years, with the last transfer in August 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 146 m² the property is well over the postcode median (107 m² across 10 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £1,057,000 sits 154.7% above the 2009 sale of £415,000. On a £-per-square-foot basis, the last sale (£264/sq ft) was about 45% below the postcode norm.
