CommSec Home Size Trends Report: Smallest homes in 17 years

CommSec Home Size Trends Report

The average size of an Australian free-standing house has fallen to 17-year lows. Data commissioned by CommSec from the Australian Bureau of Statistics, shows the average new house built in 2018/19 was 228.8 square metres, down 1.3 per cent on a year ago to the smallest house size since 2001/02.

Seven years ago, Aussies were building the biggest detached (free-standing) houses in the world. But in the period since, Aussie home buyers have embraced apartments as well as smaller houses on smaller lot sizes. There are still McMansions being built, but there are fewer of them. Now houses being built in the US are the biggest in the world, around 5 per cent bigger than in Australia.
