Home Truth, by sustainable architecture firm Breathe, has a footprint measuring 236 sq m - the size of the average new Australian house.

The home truth of this labyrinth is that building smaller spaces could help solve the nation's housing crisis, according to Breathe founder Jeremy McLeod.
The firm is best known for its inner-city sustainable build projects, such as The Commons in Brunswick, which features gardens and rainwater harvesting.
New Australian houses are on average bigger than the United Kingdom and France, and even the United States and Canada, McLeod says.
"We live in a time of housing crisis, cost-of-living crisis, and climate crisis, and our response to that is to build the biggest housing in the world," he told AAP.
"What we're saying here is, this is the truth about where we're at. What are the possibilities? What could we do differently?"

Smaller homes can be better quality, more sustainable, and improve our sense of community, McLeod said.
He has welcomed a recent blitz on housing policy by the Victorian government, saying the state needs more innovative housing options - but so too does the rest of the nation.

These have been put together using only nails and screws, so in a few months the materials will be re-used on housing projects.
The design was chosen from about 80 entrants for the National Gallery of Victoria's 2024 architecture commission, the ninth installation in the annual series.
Home Truth will be on display from Wednesday until April 2025 at NGV International in Melbourne.
