Robot arms used to pipe the concrete walls out like icing are the same you would find in BMW and Mercedes car factories, and allow for a lot of architectural freedom, from curved walls to 3D prints on wall faces.

It is accurate and efficient, with walls that take a week to put up done in just hours.

Australian company Contec said it is three-times stronger than brick, safer to build and easier on the wallet.

“It’s 22 per cent cheaper just on materials,” Contec founder Mark D’Alessandro told 7NEWS.

“That’s not factoring in the savings on less scaffolding requirements, and also the savings you have in delivering the project quicker.”

The company behind the technology say it could play an important role in solving the housing backlog.

Just a slab just five months ago, the completed house will go on the market next week.

Under a normal construction timeline, it likely would not even be at lock up yet.

Smaller housing companies are already showing interest, but brickies have been told not to worry.

“It does have it’s place, but it’s very much still in its infancy and very much still a cottage industry,” Master Builders chief executive Matthew Pollock told 7NEWS.

“I’d be more worried if I was a paralegal these days just going through uni and AI taking my job.”
