If you had to describe the work of New Orleans–based Trahan Architects according to only one essential element, it would be materiality. Take the Alliance Theatre in Atlanta, where Trahan partnered with sculptor Matthias Pliessnig on the overhaul of a historic 650-seat auditorium. The interior of undulating ribbons fabricated from steam-bent white oak inspired a “wow” from the design judges, who lauded the firm’s “dramatic, sumptuous, and well-detailed” projects that offer “beautiful, compelling spaces to dwell within.” The firm’s portfolio helped Trahan earn the Number One spot for Design in this year’s Architect 50.
The idea for the Alliance’s design came after an African American member of the community recalled how the theater, which opened in 1968, once had segregated seating. “It was critical to address the issue of equality and diversity, and so we challenged ourselves to shape a space where the lower level and the balcony level could integrate into one unified community,” says Trey Trahan, FAIA, the founder of the firm, now 35 employees strong but rapidly growing.

Transforming complex conceptual ideas into realized physical spaces is no simple task, but Trahan Architects excels at this alchemy. “Sometimes our focus is on the artistry and on shaping things that are beautiful, but at other times the focus is on marrying technology and our commitment to ecology,” Trahan says. With Alliance, which won a 2019 R+D Award, “we found, through the use of technology, that we could very cost-effectively build these shaped pieces consistent with the placement of each strand in the digital model.”
Material, Trahan says, is critical to that process. “Buildings should become more harmonious with their context over time and the environmental conditions should result in a patination that is rich and touches us in an emotional way,” he says. “We’re attempting to work from both a cognitive and emotional place.”

At the Conservation Foundation Headquarters in New Orleans, for example, their design couples a cast-in-place concrete box with a weathered steel sculpture wall that creates a tranquil and contemplative respite within the bustle of the city’s central business district. That process extends to their robust pro-bono work for clients like Hubbard Street Dance in Chicago. Last year, Trahan helped the company with site evaluations for a new building while completing a concept design for a temporary space.
“It’s beyond buildings, right?” says Trahan. “It’s about arriving at a place where you believe that architecture can create or result in an attitude of kindness. … Architecture has a voice in that.”
