Space Caviar: The Latest Architecture and News

Cities today are being reimagined as living, evolving organisms, combining digital intelligence, ecological systems, and new materials to shape radical futures. At Carlo Ratti's "Intelligens. Natural. Artificial. Collective." biennial, over 750 participants challenge established boundaries between architecture, landscape, and technology. Several conceptual projects showcased in the main exhibition challenge conventional boundaries between architecture, landscape, and technology. From bio-adaptive urban systems and Martian water-based settlements to immersive symphonies of satellite data, these works collectively envision new models for cohabitation, resilience, and planetary awareness.

This month's Unbuilt selection presents six speculative projects, presented as part of the 2025 Venice Architecture Biennale exhibition, as provocations for rethinking the future of cities and human settlement. While some proposals transform architecture into self-sustaining, living infrastructures, others explore how data and sensory interfaces can redefine our relationship with natural and urban environments. Together, they offer a cross-section of how architects and designers are using unbuilt work to imagine new possibilities for life on Earth and beyond.

The 19th International Architecture Exhibition, organised by La Biennale di Venezia under Carlo Ratti's curatorship and the theme "Intelligens. Natural. Artificial. Collective," is set to transform Venice into a "Living Laboratory" of experimentation and collaboration. This year's special projects extend beyond the exhibition grounds, integrating into various city locations and Forte Marghera in Mestre, providing an alternative perspective that expands the reach of architectural discourse.

The Biennale promises to be a dynamic platform uniting over 750 participants from diverse backgrounds, including architects, engineers, mathematicians, climate scientists, and artists. Such a broad coalition of over 280 projects underlines the Exhibition's focus on inclusivity and interdisciplinary collaboration, an essential aspect for adaptation. The selection process proposed a bottom-up, open call approach through the Space for Ideas initiative, which ran between May and June 2024. It encouraged participation from global teams, from Pritzker Prize winners and Nobel laureates to emerging architects and scientists.

Genoa-based studio Space Caviar has recently unveiled Arcipelago di Ocno, an aquatic installation on a lake in Mantova, Italy, which is the 2016 Italian Capital of Culture. Named after the local demigod Ocno, the installation recalls the form of a lotus, a plant with an extensive presence in Mantova’s lakes.

Acting as an aquatic piazza for the city, the archipelago of floating islands “[extends] Mantova’s urban fabric onto the lakes that surround its historic center,” utilizing modular units to create a venue for Mantova’s cultural activities for years to come.
