Building a tool shed will take on a new meaning for the Hannah Bay Reserve Community Garden this weekend.
The shed will be built from old tyres filled with compacted dirt using a process called Earthship building.
Project manager Ian Hewison said the new building was a great way to show the concept of recycled construction.
"Earthship buildings are machines that look after humans as they catch water for drinking and cleaning, store heat through thermal mass and provide a sustainable way to live," he said.
"They are made from materials indigenous to every country, such as bottles and cans and are virtually free to run."
