At the intersection of architecture, technology, and sustainability, Diller Scofidio + Renfro (DS+R) presents Canal Café, a provocative installation for La Biennale di Venezia 2025 that transforms the brackish waters of Venice’s canals into the purest Italian espresso. Part espresso bar, part ecological experiment, the project challenges perceptions of urban water systems while delivering an unexpected sensory experience—Venice in a cup.
The Arsenale Lagoon, the lifeblood of Venice’s maritime history, is both a symbol of beauty and a source of environmental anxiety. Rising sea levels, pollution, and mass tourism threaten the delicate balance of the city’s waterways. Canal Café confronts these issues head-on, reimagining contaminated water as a resource rather than a liability. The installation’s hybrid purification system merges natural and artificial filtration to produce drinkable water with a distinctly Venetian minerality.
A transparent pipeline draws water from the lagoon, guiding it through a bio-filtration system that removes sludge and toxins. The process splits into two streams: one passes through a micro-wetland where salt-tolerant halophytes purify the water while preserving its natural minerals; the other undergoes reverse osmosis and UV disinfection for complete sterilization. The two streams are then recombined, steamed, and pressed through locally sourced coffee grounds, resulting in an espresso that carries the essence of Venice.
Beyond its function as a public coffee bar, Canal Café serves as a living laboratory, demonstrating how urban water remediation can be both functional and poetic. The unused purified water nourishes an adjacent landscape installation, closing the loop in a cycle of sustainable reuse. Collaborating with Natural Systems Utilities (USA) and Sodai (Italy), DS+R merges cutting-edge engineering with ecological design, proving that infrastructure can be experiential.
By inviting visitors to “drink Venice,” Diller Scofidio + Renfro blurs the line between art and utility, offering a bold commentary on climate adaptation, resource scarcity, and the future of water-sensitive design. The project doesn’t just serve coffee—it serves a vision of resilient cities, where every sip is a reminder of what’s at stake.
Recognition came swiftly – at the 2025 Venice Architecture Biennale’s awards ceremony, Canal Café was awarded the Golden Lion, the exhibition’s highest honor. The jury celebrated DS+R’s work as “a catalytic demonstration of architecture’s ability to reframe ecological crises through radical hospitality”, particularly praising how the project “transforms public anxiety about water into communion and delight.” For those attending La Biennale, the installation now offers not just a taste of Venetian innovation, but the chance to experience what the jury called “the most compelling prototype for climate-conscious design at this year’s exhibition.”
