STL is a collaborative group of design professionals with a common vision and a passion for architecture, planning, and design.

Founded in 1996 STL is led by Luis Collado, Jose Luis de la Fuente and Tracy Susanne Salvia. We have enjoyed successful working relationships with many clients, both large and small, and have firmly established STL as one of the premier architectural firms in Chicago.

We believe that good architecture evolves through humble, team-based efforts. Hence, our office thrives in an open and communicative atmosphere, which favors cohesiveness and directly benefits our projects.
