Architect & Founder

Prescott Muir, FAIA

Prescott Muir founded the practice in 1976 with an instinct that architecture should do more than satisfying need, it should reveal hidden potential. Five decades later, that belief continues to evolve through Muir Architects, a practice built around collaboration, curiosity, and an enduring commitment to design. Working alongside a select group of colleagues and collaborators, Prescott remains deeply engaged in the work: listening to new and returning clients, exploring possibilities with them, and helping transform aspirations into meaningful solutions. Muir Architects represents both a continuation and a new chapter, exploring how thoughtful design can respond to changing ways of living, working, community, and thinking about buildings.

The ambition extends beyond the success of any single project. It is to create architecture that contributes to something larger, strengthens communities, reinvigorates neighborhoods, anticipates new technologies, and finds meaning in the places we share. For Prescott, architecture remains an evolving practice, one that demands curiosity, relevance, and the willingness to continually test assumptions.

Prescott’s career has moved fluidly between practice, writing, education, and mentorship, each informing the way he thinks about architecture and the best it can be. His work has received numerous design awards and has been widely published, including his monograph, It By Bit. In recognition of his contributions to design excellence, he was elevated to the College of Fellows of the American Institute of Architects.

Yet for Prescott, the greater measure of a career is not recognition, but giving back. Teaching and mentoring generations of architects has created an exchange of ideas that continues to resonate, inviting new perspectives, and pushing the discipline forward. That exchange defined his seven years as Director of the School of Architecture at the University of Utah and he continues a commitment to education as Emeritus Faculty. While he has recently stepped away from academia, the role of educator and mentor remains integral to his practice and to the culture of Muir Architects, where experience is not simply preserved, but shared, questioned, and used as a foundation for what comes next.

Prescott reflects on the people, ideas, and experiences that have shaped his career in AIA Utah’s Legends of Architecture podcast.

Prescott’s experience spans the intersection of architecture, community, and the natural environment, from urban infill to sensitive intervention in nature, his work includes nature preserves, museums, theaters, galleries, libraries, civic buildings, healthcare, affordable and transitional housing, and new community development. This breadth of work has reinforced a fundamental belief that architecture has the greatest impact when it responds not only to preservation, but to what it has the potential to create and foster new intercommunities. He is continually energized by clients who bring new perspectives to the design process and share an ambition to make a meaningful difference in local communities. Their ideas create opportunities to question conventions, explore new possibilities, and develop precise, thoughtful design responses that are inspiring.

This perspective shapes the future of Muir Architects. The practice seeks opportunities to engage with diverse communities, drawing upon the distinct character, knowledge, and aspirations of each to create places that are more connected, resilient, and sustainable.

Prescott received a Master of Science in Architecture and Building Design from Columbia University, a professional Bachelor of Architecture from the University of Southern California, and Bachelor of Fine Arts from the University of Utah.
