The adaptive reuse project encapsulates Venice’s unique water collection history, specifically its wellheads—an ingenious system vital in a land surrounded by saltwater. The project reimagines the societal and communal significance of this historical infrastructure, and evokes contemporary water conservation efforts of the future. Transforming and extending the existing site of a former naval training swimming pool ‘Piscina Gandini’ from the 1960s, the proposal is a sequential journey carved by two planes: roof and ground as water collection, skylights and filtration surfaces, blurring the boundaries between a path and a building. Reinvented pitched roofs collect rainwater while reclaimed terracotta tiles aid in natural cooling and energy storage. The immersive journey through water’s historical significance exhibits the evolution from early water collection systems, the social fabric and communal order they wove, and climaxes at the intersection of waterspines, where the transformed piscina building becomes a contemporary exhibit of collecting, consuming and experimenting with water processes. The museum experience thus transcends typical enclosure boundaries, offering diverse encounters with water. By both honoring and projecting forward from Venice’s water history, the project aims to deepen public awareness about water processes, advocating for their conservation as crucial resources for a sustainable future.
