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.

“I think the key to success is that you have to be a good designer, you have to be able to sell good design, and you have to be able to sell yourself. They’re all bundled up together…You have to keep clients happy not just by doing what they say, but by doing really great design and having them understand and endorse and embrace it”
