diller scofidio and renfro venice canal water coffee wins golden lion 2643348

Diller Scofidio and Renfro (DS+R) has won a Golden Lion at the 2025 Venice Architecture Biennale for "Canal Café," a project that brews espresso using water filtered from the Venetian lagoon. The installation, part of the biennale's exhibition "Intelligens. Natural. Artificial. Collective," uses a combination of biological filtration by salt-tolerant halophytes and artificial methods like reverse osmosis to purify the polluted canal water. Michelin-starred chef Davide Oldani selected the coffee blend, and the espresso is sold for €1.20. Originally conceived for the 2008 biennale but delayed due to permit issues, the project was realized with improved filtration technology and support from engineering firms Natural Systems Utilities and SODAI, as well as Webuild.
