This project contributes to the discourse on the sublimity of water through an architectural lens, focusing on Cockatoo Island's history and ecology. It proposes a museum that memorialises water and addresses environmental challenges, emphasising a response to the climate crisis. It utilises a framework of principles to enact this; Introspection, Symbiosis, Porosity and Journey. It is additionally underpinned by sustainable practices, like an algae farm and advanced water collection, to transform Cockatoo Island into a beacon of spiritual and custodial architecture and prompt an individual response to climate change.
