TGDA thrives because of our highly collaborative and supportive design studio culture. TGDA’s Design for Life ethic, which creates beautiful, iconic public spaces to promote healthy living, is infused into every aspect of our practice. Our thoughtfully selected and professionally trained staff share capabilities and interests to support growth, creativity, success and a healthy lifestyle, both in and out of the office. We design to connect people with vibrant and ecologically thriving places in local neighborhoods, regionally celebrated open spaces, and campuses and estates, for the benefit of our diverse clients and their communities.
Given the significance and scale of our projects, TGDA collaborates closely with clients and design teams, providing direction and vision to integrate natural systems for buildings and sites. TGDA’s unique niche has developed as a result of our leadership and innovation in the design field, which has enabled us to attract a diverse, accomplished talent pool to Chicago. Our open studio space encourages interaction, drawing, and the testing of a range of ideas, which consistently flow through the office. Our team practices with a passion for connecting people with nature through the development of diverse landscape solutions that emphasize our "Design for Life" approach.
