Average house size in Australia 

Let’s take a look at what the average size of a house in Australia is, and what can influence this.

The average size of houses in Australia

According to CommSec, the average size of a house in Australia completed in 2020/21 is 195.8 square metres, down by 0.4 per cent from those completed in 2019/20. Moreover, the average size of free-standing houses completed in Australia in 2020/21 was 229.3m², meaning such houses were approximately 6.5m² smaller than those completed in 2019/20. This shows a slight down in the average size of houses in Australia, which has been on the rise in the past few years.

The structure of average-sized homes in Australia

A normal house in Australia built for an average family requires at least three bedrooms, two bathrooms, and a garage. An average family also wants a home that is at least 200 square metres in size. These are the minimum requirements for most families, but there are always exceptions. Some families need more space, while others can get by with less.

Factors that influence the average size of homes in Australia

  • Price range/budget 

This can vary depending largely on whether you want to buy or build a house. Real estate industry statistics for Australia indicate that housing prices went down during the initial phase of the Covid pandemic. On average, building a house is cheaper than buying one. In Australia, the prices of average new houses built range from $268,800 upwards for 3-bedroom houses and $481,268 upwards for 4-bedroom ones. In comparison, buying an average house in some parts of Australia can cost you up to $1 million.

  • The climate

If you live in areas where the climate is somewhat extreme (cold winters, hot summers, floods), more building material is needed to properly insulate houses, which means more money is needed for building or buying a house. Also, some climate conditions require smaller houses (in winter, it’s warmer if you live in smaller houses because they get warm more quickly), and some larger (bigger houses retain less heat and have cooler temperatures).

  • Location

Another essential factor that families consider when choosing a home is its location. This includes the part of the country the house is in, as well as the city and neighbourhood where it is located. If you’re choosing a new family home, you’ll probably want to live in a neighbourhood with good schools, which can cost more.
