The Holcim Foundation for Sustainable Construction has announced the 20 winning projects of the 2025 Holcim Foundation Awards, recognizing contributions to sustainable design and construction across five regions: Asia Pacific, Europe, Latin America, the Middle East and Africa, and North America. This year's selection spans a broad range of scales, from a 200-square-meter semi-permanent school in a Kenyan forest to major urban regeneration initiatives in Madrid, Dhaka, and Shenzhen, reflecting the diversity and reach of sustainable architecture today. This year introduces a new Grand Prize format, replacing the traditional Gold, Silver, and Bronze rankings. Each region will now honor one Grand Prize winner, emphasizing excellence without comparison and acknowledging the diverse approaches to sustainability.
The Holcim Foundation's four goals, Uplifting Places, Healthy Planet, Thriving Communities, and Viable Economics, along with its guiding principles of being Holistic, Transformational, and Transferable, continue to shape the jury process. The regional juries were chaired by Sou Fujimoto (Asia Pacific), Kjetil Trædal Thorsen (Europe), Sandra Barclay (Latin America), Lina Ghotmeh (Middle East and Africa), and Jeanne Gang (North America).
All winners will be celebrated at the 2025 Holcim Foundation Awards Ceremony, taking place in Venice on November 20, 2025. The event will bring together leading figures from architecture, design, and construction, with the announcement of the five regional Grand Prizes serving as the evening's highlight. ArchDaily joins the Holcim Foundation as the official media partner for this year's ceremony and will host a live stream, providing a global audience the opportunity to watch the announcements in real time and learn about the recognized projects in sustainable construction. Registration to access the live feed of the Holcim Awards 2025 Ceremony is now open.
