Today, we’re building on our legacy of success and client satisfaction
Studio Hillier LLC is an interdisciplinary design firm in Princeton New Jersey, co-founded in 2011 by Partners Barbara A. Hillier, AIA and J. Robert Hillier, FAIA, PP. Together for over forty years, they formed the backbone of a vibrant, growing, full-service design studio that has the depth of experience and design talent to take on any challenge. Since Barbara’s passing in 2022, Bob has been carrying on their shared legacy as the firm’s Managing Principal. Studio Hillier is located in the heart of the historic Witherspoon-Jackson neighborhood in Princeton, New Jersey and operates out of a transformed machine shop and warehouse.
We work collaboratively with experts in the region and elsewhere who bring excellence and robust knowledge of the latest building technologies, prefabrication systems, environmental systems and preservation of historic structures.
Our success is reflected in the number of repeat clients who recognize our rigorous standards of performance in meeting occupancy dates, managing the budget and delivering high quality professional services. With hundreds of design awards, our reputation for excellence is evidence of our commitment to our clients, to place, sustainability and the built environment.
