Philip Castillo

Jahn is among the most iconic names in architecture. Founded 60 years ago, our studio has reshaped cities and changed minds with a group of professionals sharing the same passion for architecture, design, and technology. Our approach is based on the principles of integrated design, cultural and site-specific research, and close collaboration with our clients and partners. Powered by the people and ideas it brings together, our work spans four continents and encompasses a range of typologies and scales. We come to the studio from different places and perspectives, equipped with multiple talents, abilities, and backgrounds. From our office in Chicago, our architects and designers collaborate with the most innovative engineers, fabricators, and builders to create architecture of authenticity and integrity. Through it all, we have never stopped changing. Inspired by the ideals embodied by our founders, Charles F. Murphy, Sr. and Helmut Jahn FAIA, we are just as restless and curious as we were in 1937. Today, our studio prizes a vibrant, diverse, and co-creative culture where ideas are ceaselessly tested and challenged. Guided by the veteran team of Evan Jahn, Philip Castillo FAIA, and Steven Cook FAIA, we have opened new paths of aesthetic and construction discovery, putting to use the most current materials and research available. The result is a body of work that speaks for itself, addressing urban responsibility, performance, engineering synthesis, attention to detail, and sustainability by design. We are a group of doers, darers, designers that are grounded in our values, unbounded by convention and energized by the future. Having trust in our creativity, and by allowing space for experimentation, we believe we can design a better world.
