The exhibition is built on the idea that envisioning the future is a way of shaping it. It invites forward-thinking urban advocates to imagine a better future for Catalonia and the world, addressing the common challenges most citizens face. "Somia la Ciutat" explores the evolving trends in urbanism and architecture, driven by three key forces: the green movement, evolving identity, and the digital revolution.

"The exhibition charts new pathways for the future of cities, blending conscious planning with radical optimism," says Roger Subirà.

The featured projects, presented through images, videos, or models, are accompanied by simple, accessible ideas, statements, or questions. Together, these elements form a collage of possible future scenarios, inviting visitors to reconnect with optimistic visions for the future of cities. This approach of conscious optimism is seen as both revolutionary and essential for today's challenges.

In the Green Revolution room, amid a moss-covered environment, IAAC’s installation TREEdimensional stands out—a tower prototype exploring the use of wood as a 21st-century building material, emphasizing the relationship between nature and urban spaces. The project highlights the importance of integrating natural elements into cityscapes.

This room underscores the transformation of urban and architectural experiences focused on sustainability, with green as the dominant theme. The projects are displayed in environments reminiscent of public spaces, incorporating urban systems that support drainage and pollution absorption, with wood playing a significant role.

By 2050, 68% of the global population is expected to live in urban areas. Whether by necessity or choice, these spaces must be secure, healthy, and habitable. In light of climate change, cities need to evolve into sanctuaries that mitigate its impact. Expanding urban green spaces requires moving beyond aesthetics, recognizing nature’s potential to create profound structural changes. While the 20th century saw cities dominated by cars, the future envisions reclaiming urban space and exploring new possibilities.

The exhibition also features contributions from renowned architecture and design firms such as 300,000 km/s, Andrés Jaque's Office for Political Innovation, Archikubik, BIG – Bjarke Ingels Group, Cobe Architects, ecoLogicStudio, EMBT Benedetta Tagliabue, MVRDV, RCR Arquitectes, Safdie Architects, Snøhetta, Takk Architecture, Tatiana Bilbao Studio, and Zaha Hadid Architects, among others.
