Overview

About 20 Brookside Avenue

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

20 Brookside Avenue is a three-bedroom semi-detached house in Southampton (SO15 4HZ). It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (August 2013) shows a D (score 67), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since May 2011. Between certificates, window efficiency went from Poor to Good; while lighting dropped from Average to Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from August 2013, so improvements made since then won't be reflected. Period features are noted in the property record. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.

Across 2012–2022, sale prices on this property compounded at 8.8% per year. On a £-per-square-foot basis, the last sale (£339/sq ft) was about 67.1% above the typical sold price in the postcode. Most recent transfer: February 2022 at £350,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
