About 46 Brookside Avenue
46 Brookside Avenue is a three-bedroom semi-detached house in Southampton (SO15 4HZ). It has a recorded floor area of 88 m² (around 947 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (February 2016) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in April 2015 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Very Poor to Very Good and lighting went from Poor to Average; while window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Average. The recommended improvements would push it to C (score 79). The latest certificate is from February 2016, so improvements made since then won't be reflected.
Held since February 2008 — that's 18 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £330,000 sits 71.9% above the 2008 sale of £192,000. One planning record on file: an extension approved in 2025. Past consents include an extension, meaningful when judging how the property has evolved.
