Earlier this year I visited the Greenhouse by Joost in Federation Square, Melbourne.
It was a wonderful example of design innovation, sustainability and education, and there was a great brochure that went through all the inspiration and process behind it. Joost had worked in hospitality for many years, and had created wonderful events, but was appalled by all the waste. Creating the Greenhouse from all recycled materials, and then leaving no 'footprint' was a fantastic example of what can be achieved. Innovative methods of construction that hadn't been done before were successfully tried, and the restaurant served produce that had been grown on the green roof.
There will now be a permanent Greenhouse in Perth.
