The team behind BRICKX includes buying agents and two other advisers in addition to Mr Lawless – Colliers International's Peter Chittenden and realestate.com.au's chief economist Nerida Conisbee.

"I am struck by how low the model makes barriers to entry into property," Mr Lawless said. "You can buy in without the high commitment, diversify your portfolio and use it for hedging [to access expensive suburbs]."

Each property is split into 10,000 bricks and no one investor can buy more than 5 per cent of the bricks, so the minimum number of investors is 20. "So you can't have a takeover, unlike the stock exchange," Mr Millet said.

BRICKX has five initial properties for investment – three apartments in Mosman, Enmore and Double Bay, a house in Annandale (all in Sydney) and an apartment in Prahran in Melbourne. BRICKX sticks to tier-one properties priced between $500,000 and $1.5 million.

Each property is underwritten by BridgeLane but it does not own the properties, which are instead placed in trusts and managed by the trustee – Theta Asset Management – which also acts as the property's responsible entity. It fully distributes the net income on properties to investors monthly. BRICKX makes a 1.75 per cent commission for every brick transaction.

At the end of five years, it is investors who decide to continue, or discontinue, with their investments. At any time, 50 per cent of each property's investors can also decide to wind up the investment.

But every investor can sell their bricks to another investor using the trading platform any time.

The business, now a scheme approved by the Australian Securities and Investments Commission, already has close to 200 pre-launch investors who have invested $400,000 in bricks.

While BridgeLane is known for its many "disruptor" businesses including tech company Amaysim, and services marketplace Airtasker, BRICKX was not one of them, Mr Millet said. Rather, it was a long-awaited business poised to revolutionise property investment.
