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.
CRA–Carlo Ratti Associati and Höweler + Yoon have unveiled images of AquaPraça, a floating gathering space for global climate dialogue set to anchor COP30 in Belém, Brazil. Currently under construction in northeastern Italy by steel construction company Cimolai, the project will be unveiled at the 19th International Architecture Exhibition of La Biennale di Venezia on 4 September 2025. It will then embark on a transatlantic journey to Brazil, where it will form part of the Italian Pavilion at COP30, held from 10 to 21 November 2025. Following the event, it is intended to become a permanent floating landmark in the Amazon as part of Belém's cultural infrastructure.
The Pavilion of China at the 19th International Architecture Exhibition - La Biennale di Venezia presents the exhibition CO-EXIST, curated by Ma Yansong, founder of MAD Architects, and organized by the Ministry of Culture and Tourism of the People's Republic of China at the Arsenale. Through ten works by twelve interdisciplinary groups, the pavilion examines how traditional Chinese philosophical thought can inform architectural responses in the age of advanced technology and artificial intelligence.
"The limits of our design language are the limits of our design thinking". Patrik Schumacher's statement subtly hints at a shift occurring in the built environment, moving beyond technological integration to embrace intelligence in the spaces and cities we occupy. The future proposes a possibility of buildings serving functions beyond housing human activity to actively participate in shaping urban life.
Artificial intelligence (AI) is no longer a futuristic idea in architecture — it is a concrete reality that is reshaping how we design. In seconds, computational systems can process and evaluate a wide range of variables — formal, programmatic, contextual, and regulatory — guiding architects toward highly optimized solutions. But as we embrace this algorithmic revolution, a critical question arises: can architectural intelligence be reduced to data-driven logic? In response, alternative approaches are gaining momentum — ones that value ways of building grounded in sensory experience, adaptation to place, and the intergenerational transmission of knowledge. In the exchange between artificial and ancestral forms of intelligence, a deeper understanding begins to take shape. Intelligence does not reside in the tools themselves, but in the intention and sensitivity with which we use them to navigate complex realities.
The 2025 edition of the VeniceArchitecture Biennale is hosting a total of 65 National Pavilions. Among them, four countries, Azerbaijan, Oman, Qatar, and Togo, will be participating for the first time. The exhibition will unfold across three main locations: 26 pavilions at the Giardini, 22 at the Arsenale, and 15 spread throughout Venice's city center. The exhibition will bring together over 750 participants, forming interdisciplinary and multi-generational teams, and is anticipated to be the largest in the Biennale's history.
In recent weeks, cities around the world have introduced new policies, recovery efforts, and infrastructure projects that reflect growing pressure to adapt to climate realities. From Southern Europe to South America and the United States, these urban updates address both immediate challenges and long-term shifts in how the built environment is governed, designed, and inhabited. Some initiatives focus on regulation, tightening building codes in fire-prone areas or reforming aging safety systems, while others spotlight large-scale investments tied to global events such as COP30 and the Venice Architecture Biennale. This edition of Architecture Now gathers a selection of city-led actions and collaborative efforts that point toward a more resilient, responsive future for architecture and urban life.
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.

French architecture studio Coldefy and Italian architecture practice CRA-Carlo Ratti Associati have completed the 'Theatre of Life,' the project selected as France's national pavilion at Expo Osaka 2025, and welcomes visitors until 13 October. The pavilion welcomes both natural and artificial habitats, aiming to illustrate how design can connect human and non-human worlds while showcasing France's contribution to culture and the natural environment. In the exhibition, the visitors are invited to explore France's multiple ecosystems and rediscover a connection to nature.
Expo 2025 Osaka has officially opened on April 13, 2025, at Yumeshima, Osaka. Under the overarching theme "Designing Future Society for Our Lives," the Expo set out to explore three pivotal subthemes: Saving Lives, Empowering Lives, and Connecting Lives. These themes aim to unite architectural and design enthusiasts by demonstrating how cutting-edge technology and innovative solutions can address global challenges, foster dialogue inspire collective action.

The official torches, named Essential, for the Milano Cortina 2026: Winter Olympics and Paralympics, were unveiled in parallel events at the Triennale di Milano and Expo 2025 in Osaka. Designed by Carlo Ratti Associati in collaboration with Eni and its subsidiary Versalis, Essential takes a minimalist approach that foregrounds the flame as the central element. The project blends Italian design with engineering precision, resulting in a torch that serves as both a symbolic and technical object. Its open structure, uncommon in torch design, allows viewers to see how the flame is produced, revealing the typically hidden mechanisms at work.
