Creating an educational setting is a specific and sensitive task. Merging children's safety and learning optimization requirements with an aesthetic appeal and solid concept can birth some of the most beautiful, unique projects around. One common configuration is the elliptical or circular school. A circular, more specifically ringlike educational setting can suggest a sense of protectiveness and safety with the construction of the embracing surrounding membrane. It is also a practical setup that envelopes multiple functions while linking them, consequently allowing interactive instances through the central courtyard.

CHYBIK + KRISTOF (CH+K) has unveiled new images of its multi-purpose arena in Jihlava, a progressive city in the heart of the Czech Republic. Designed as part of a winning competition proposal in 2019, the project is being developed for the local ice hockey team, HC Dukla, and is scheduled for completion in late 2025. The arena has recently reached a key milestone with the installation of its characteristic facade. Unlike many similar developments that relocate to the outskirts, the venue retains its central position, an intentional decision by the municipality to activate the city core, support local businesses, and ensure accessibility by public transport and on foot. The project aims to enhance public life while contributing to the city's long-term sustainable growth.

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 first edition of the Venice Architecture Biennale took place in 1980, immediately revealing its role as a platform for images and ideas that would become essential references in contemporary architectural theory and practice. This disruptive character was embodied from the very beginning by the strangely familiar floating structure designed by Aldo Rossi, titled Teatro del Mondo. At once temporary and archetypal, the project introduced central themes that would shape Italian architectural discourse in the years that followed. To this day, it continues to inspire reflections on timelessness, imagination, and the memory embedded in cities.
