Trey Trahan: Bridging Cultures, Building Community

New Orleans-based architecture firm Trahan Architects is known for their rooted approach to architecture—expressing the unique cultural, historical and ecological characteristics of the places they build. During frequent visits to Japan, Founder & CEO Trey Trahan, FAIA, has developed a passion and deep reverence for Japanese art and culture. Throughout his visits, he’s also discovered the numerous parallels between the shared ecologies of his native state of Louisiana and Japan that have permeated his firm’s approach to architecture. He and his firm have been celebrated for their depth of research, dedication to craft, sensitivity to the landscape and innovative material applications—all heavily influenced by Japanese traditions.

When he was invited to interview for the design of the U.S.A. Pavilion at Expo 2025 in Osaka, it was a dream come true. Having amassed a large collection of Japanese artifacts and artwork and developed many personal friendships over the years, his enthusiasm and connections won his firm the commission. Throughout the Expo’s six-month tenure, the U.S.A. Pavilion was consistently one of the most popular—drawing average crowds of 10,000 people per day and welcoming the world to experience the wonders of the United States of America through the narrative aesthetic lens of its host country.

Tonight, Trey will guide us through how his relationship with Japanese sensibilities—embracing chance, focusing on materiality and exercising a quiet restraint—helped guide his firm’s design for the U.S.A. Pavilion and continues to resonate in their work.
