The 5th Seoul Biennale of Architecture and Urbanism opened on September 26 at Songhyeon Green Plaza in central Seoul. Recognized as the largest public architecture festival in Asia, this year’s edition is directed by Thomas Heatherwick under the curatorial theme of how cities can become “radically more human.” Running through November 18, the Biennale brings together exhibitions, global forums, and citizen-led projects to examine the role of architecture in shaping more inclusive and enduring urban environments.

A central feature is the “Humanize Wall,” a 90-meter-long, four-story-high installation composed of 1,428 steel tiles inscribed with contributions from citizens, scientists, and designers. The structure presents 400 projects from 38 countries, designed by 110 architects, and forms a twisting gateway that frames a manifesto advocating new perspectives on architecture and urban life. Conceived as an open-air exhibition, the wall invites visitors to engage with its images and texts at multiple levels of detail.

Nearby the Humanize Wall, 24 “Walls of Public Life” present large-scale building fragments designed by international teams. Measuring 2.4 meters wide and 4.8 meters high, these fragments illustrate diverse approaches to rethinking the exterior of buildings. The contributors span multiple disciplines and cultural backgrounds, including chefs, artisans, architects, and engineers from Korea, Burkina Faso, India, China, Japan, the United States, and the United Kingdom.

These include grassroots initiatives involving more than 500 Seoul residents reflecting on how architecture influences emotional experience; “Emotionally Yours, Seoul,” a participatory digital installation built from public submissions of building facades and associated feelings; “The City’s Face,” which features 25 projects from 21 cities focused on human-centered design; and “From a Bird’s Eye to the Human Eye,” which highlights 18 new architectural works shaping Seoul‘s future from an experiential perspective.
