Overview

About 11 Barnsbury Avenue

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

11 Barnsbury Avenue is a mid-terrace house in Aylesbury (HP20 1NL). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (June 2013) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from June 2013, so improvements made since then won't be reflected.

Untraded for 18 years, with the last transfer in November 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. One planning application is currently pending a decision in 2026. Across 1997–2008, sale prices on this property compounded at 8.8% per year. Today's modelled estimate of £333,000 sits 53.5% above the 2008 sale of £217,000. On a £-per-square-foot basis, the last sale (£240/sq ft) was about 15% above the typical sold price in the postcode. At 84 m² it's 20.5% larger than the typical home in the postcode (70 m² median across 28 EPCs).
