Passers-by can peer into their kitchen and the patio garden the couple have tended for months, yielding everything from pumpkin to beans and pomegranates, and which also boasts a bee hive.
The couple will host $395-per-head dinners from January 30 and give $10 tours of the house. Guest experts will present free live-streamed talks on topics such as architecture and mushroom growing.
The house, called Greenhouse By Joost, is the idea of environmental advocate Joost Bakker, who has contributed $150,000 to the project.
His mother, Lia Bakker, invested $500,000 from the proceeds of the sale of her Monbulk farm. When the Federation Square project finishes in April, the Greenhouse will be moved to her new property for her to live in.
Mr Stone and Ms Barrett, who have starred on TV show MasterChef and who until last year were executive chefs at Oakridge Wines in the Yarra Valley, said they’ve loved learning everything from how to make milk from tiger nuts, to how to raise trout, yabbies and barramundi in an aquaponics system that uses fish poo to fertilise plants.
But the couple’s main aim is to inspire others to grow and make their own food.
“I think after COVID, people are ready to make changes in their lives,” Ms Barrett said.
“They’re focusing on their homes. They want to be connected with nature. And if you do live in the inner city, here’s the perfect way to do that.”
Mr Stone advised newbies to start with parsley, basil and tomatoes in pots. “It’s not going to change overnight, it’s about small steps.”
The Greenhouse also showcases sustainable building. The kitchen wall tiles are made from old skateboards, while the wall panels are derived from recyclable and biodegradable wheat straw.
The stairs, cupboards and tables are made of wood from fallen sugar gum and cypress trees.
Federation Square acting chief executive Suzana Bishop said the organisation supported the Greenhouse as “a way to showcase sustainability and show what the future of living sustainably can look like”.
