Infrastructure has long defined the backbone of cities by linking people, landscapes, and economies through systems that often go unnoticed until they fail. Today, as global challenges demand more adaptive and human-centered responses, architects are rethinking what infrastructure can be: not just a framework for movement and utility, but a catalyst for ecological restoration, cultural continuity, and civic imagination. The following unbuilt projects, submitted by the ArchDaily community, explore this expanded role of infrastructure, where airports, bridges, industrial parks, and pedestrian networks become architectural expressions of connection and care.
2025 promises to be a landmark in architecture, heralding a vibrant renaissance of creativity and exploration. As societies confront challenges such as climate change, rapid urbanization, and technological evolution, architecture is both a mirror to these dynamics and a compass pointing toward a sustainable and inclusive future. This year's architectural calendar offers abundant opportunities to celebrate the discipline's transformative power — from boundary-pushing festivals to thought-provoking exhibitions that explore pressing cultural and environmental narratives.
From well-established biennials to inaugural gatherings, including the World Architecture Festival 2025, Desert X Al Ula, and the COP Climate Conference, the 2025 calendar highlights themes such as sustainability, heritage, and community. These events underscore architecture's unique ability to shape a better future, addressing global challenges while honoring cultural diversity and design ingenuity.

Saudi Arabia, a country going through a tremendous transition, is not only changing its skyline but also redefining its identity on a global level. As part of their 2030 Vision serving as the compass, the kingdom is moving toward new developments, aiming to revive culture and diversify the economy. In fact, the capital, Riyadh, is leading the transformation by hosting the 2030 World Expo. Representing the country’s dedication to advancement, several mega projects are taking place and transforming the kingdom's fabric.
Amidst the various projects, many world-renowned firms are working on these mega projects at many different scales. For example, the cultural renaissance is shown through Snøhetta’s Opera House in Diriyah, while the Jeddah Tower is on a trajectory that will overtake the Burj Khalifa. In the meantime, Heatherwick Studio’s conversion of a Jeddah desalination plant into a thriving cultural center showcases their repurposing of industrial spaces. From coastal projects by Foster + Partners to city center skyscrapers that are redefining the skyline, the country is undergoing significant transformations in its built environment.
The First Islamic Arts Biennale, artistically directed by Sumayya Vally, opened on January 2023 and is still ongoing until May 23, 2023, in Jeddah, Saudi Arabia.
