About Us
Jahn is among the most iconic names in architecture. Founded more than 60 years ago, our studio has reshaped cities and changed minds. Jahn continues to evolve pushing the boundaries of design, advancing building technology, and shaping the next generation of cities. From transformative towers to engaging community spaces, our work is focused on creating timeless, impactful architecture that shapes the future of the world around us.
Our continuous curiosity for exploration is not limited to a specific typology or scale and is energized with each new opportunity.
Today, that legacy is carried forward by a collaborative studio culture led from Chicago by Evan Jahn, Assoc. AIA, WELL AP, LEED AP ND, Philip Castillo, FAIA, and Scott Seyer, AIA, LEED AP. Working alongside leading engineers, fabricators, and builders, the studio delivers architecture defined by integrity, performance, and timeless quality. By trusting creativity and allowing space for experimentation, we believe architecture can meaningfully improve how people live, work, and connect.
