Average House Size in Australia

Most childhood dreams include living in a two-storey homes with four bedrooms, a huge average room size, multiple cars, and a big lawn they can roll around in. Just like what we see in the movies. But as we grow older, we realise how impractical it can be not only because having that many rooms can be hard to clean, but also because of the home loan and interest rate that come with it. Still, wouldn’t it be nice to have your own house with a garden and a kitchen to die for?

Dreaming is free, but let’s be realistic for now and talk about the average home size we have here in Australia and where we are in the world ranking.

Australia’s typical home sizes

Trends show Australians choosing to live in smaller sized homes and in apartment units because of its distance to the city and amenities, as well as the comfort it brings.

The Average free standing house size in Australia is 228.8 square meters (m2). This is the smallest average house size built per year in Australia in the last 17 years.

Australia still has the second biggest houses in the world behind USA. This is still the case even though Australian houses have shrunk since 10 years ago in 2011/2012 when it was over 240 square meters.

Today, the combined home size (house & apartment) being built in Australia is 189.8 in square meters (m2). this is the smallest being built since two decades ago.

In reality, this statistic is distorted and houses aren’t really getting too much smaller, but there are more and more apartments are being built and occupied by Australians. In fact, it accounts up to 41% of new houses being built, which is up significantly compared to just eight years ago.

Average Apartment Size

The size of the average Australian apartment being built has been slowly been shrinking and is now 128.8 square meters. However, This size is up 3.2 percent from the previous year.

Apartments are becoming more adopted by Australian home buyers. In fact 57% of new homes built in NSW are apartments and in Australia 41% are now apartments. Australia wide, this is 14 percent higher than eight years ago. This can be attributed to home buyers and renters preferring to live closer to the city centre.

What is the average size of a 3 bedroom house?

According to Australian Bureau of Statistics, the most common house configuration in Australia is a three bedroom house making up 38.8%. Therefore, it is safe to assume the average size of a new 3 bedroom house in Australia is about 175m2 meters squared. However, older homes in Australia were generally smaller, so existing 3 bedroom homes will be significantly smaller.

This chart below shows the average % of each house bedroom configuration in Australia from 2016.

House Size by State

Victoria and Perth are currently on top of the list with newly built homes at 242m2. Queensland follows at 227m2, and New South Wales at 230m2. Tasmania and ACT have the smallest houses at 195mand 197m2, respectively.

Let’s not forget about apartment size. Even though it’s no surprise that Sydney has more apartment dwellers, Melbournians live in bigger apartments at 131m2, compared to Sydneysiders at 129.50m2.

Australian House Size VS other countries?

We used to be on the top list of biggest housing floor plans but with the increase in demand of apartment units, the average Australian floor plan decreased to 233m2. This puts us behind United States with their free-standing homes being at 240m2. Just five years ago, we were at par with them and Australian homes are still more spacious compared to other western and developed countries like Denmark (137m2) and Canada (181m2). You can see the house size based on data from census.gov.

CountrySize (m2)
United States204.3
New Zealand178.3
Hong Kong43.6

Even with decreasing floor area, we should still be thankful to the space we have available. In Hong Kong, with a population density of 6300 people per km2, people live in micro apartments and small houses with an average floor area of 43.6m2. Because of so many people in just such a small space, they don’t have the luxury of living in bigger units and free-standing homes like we do.

Today’s Lifestyle

Statistics show that on the average, at least 70% Australians still choose to reside in detached houses with at least three bedrooms, and a double garage. Average block size is around 474m2, according to National Land Survey Program.

Less than 10% live in townhouses or terraces, and unsurprisingly, more than 25% of Sydneysiders choose to live in units and apartments. Maybe it’s because of the distance from the city and amenities, accessibility to public transportation, or smaller space to clean and maintain. No matter what the reason is, each to their own, right?

  1. Help? Does the Aussie house size include the garage or exclude that space. This article should make that clear. I assume it is an additional space that houses the cars and garage paraphernalia….

    • Great point. I re-read my sources where I got the information and they don’t state this either. Generally, it is only habitable rooms. A garage is not habitable so id say you are correct.
