Those who can't make it to the dome in person can buy Cath's awesome architectural plans and engineering drawings for just AU$350 (£174/$229), meaning you can build your very own bubble home almost straight away, with minimal expenses.

Cath also shares that one day she hopes to build a sculpture park on her land, where she can display more of her art. “I will be using aircrete within the park," Cath says. "It isn't just homes that this product is useful for!" We can't wait to see how her property develops, and you can keep an eye on her progress via Facebook.
