Our Past
Since 1968 Unity Design Studio has worked on numerous projects, ranging from commercial and residential buildings to public infrastructure, community and cultural spaces. The firm's dedication to excellence and commitment to client satisfaction has earned it a reputation as a leading architectural practice. In 2023, we celebrate our 55th year in business, a significant milestone that is a testament to the firm's longevity and success. Over the years, the firm has weathered economic ups and downs, changes in the industry, and shifting trends and tastes, but has always remained steadfast in its commitment to quality and innovation. We are a studio rich in history but young in age. We are open to exploring ideas. We understand process and we know when an idea is worth pursuing or letting go. We view constraints as opportunities. We don’t rush to conclusions. We put value on relationships and we deliver excellence. We are listeners who believe that architecture born of consultation and participation will be the most responsible to the client, the community, and in turn the most meaningful.
