Trahan Architects was founded in 1992 by Trey Trahan. The firm is intimate in size but broad in its scope. Bringing together a diverse talent pool around a single shared table, our company is built on open, ongoing conversation. We engage in a collective questioning of how our process and work can contribute to the health of our ecologies, cities and economies. Each member of the Trahan team is an integral part of a collaborative process that enriches our company culture and improves the quality of our work.

Ethos: Collaboration

Leigh Breslau

“Compelling planning enriches the environment for everyone.”

After nearly three decades of experience at Skidmore, Owings & Merrill, Leigh Breslau, AIA, partnered with Trahan Architects in 2010 to open the firm’s Chicago Studio.

With a strong investment in the social mission of architecture, Leigh’s work is oriented towards serving the public and creating venues of opportunity for powerful communal experiences. He is well versed in designing state-of-the-art theatres, concert halls, museums, convention centers, sports facilities and stadia, religious institutions, federal, state and local facilities, and university and college spaces.

Leigh led the design team for Chicago’s Millennium Park, which has been recognized as one of the most successful public space projects of the last decade. He played a key role in the invention of the master plan for London’s Canary Wharf, which established a roadmap for one of the largest urban revitalization projects in the modern era. His work also includes the Dallas City Performance Hall, a “village for the arts” in the heart of the Dallas Arts District which won the Frank Lloyd Wright Honor Award (among others), and the restoration of the landmark Chicago Symphony Center Orchestra Hall which received an AIA Distinguished Building Award. In addition, Leigh has designed a series of innovative convention centers including the Virginia Beach Convention Center, and the Suzhou and Zhongshan Convention Centers in China. He is currently collaborating with Trey Trahan on the design of the Transformation of the Alliance Theatre at the Woodruff Arts Center in Atlanta Georgia.

With a personal background in performance, Leigh’s interest in the design of public and cultural spaces grew out of his love of the arts. He continues to perform as a classical pianist and is an acclaimed stage designer for Chicago’s Court Theatre. In 1978, he graduated from Trinity College with a Bachelor of Science in Biology and received a Master of Architecture in 1981 from the University of Pennsylvania. He is a registered Professional Architect in Florida, Illinois, New York and Virginia.
