In 1969, Donald C. Westphal established a small land planning and landscape architecture firm out of his Rochester, Michigan home. His passion for manufactured home community design soon became the flagship of his business, providing a level of service rarely seen in the industry. His firm soon grew into eight full-time employees, becoming one of the United States' foremost authorities on manufactured home community design. Simultaneously, the firm also expanded its services to include single-family subdivisions, RV resort design, high-end recreational facilities, commercial developments and resorts.

In 2010, Emeka Nnadi envisioned a boutique consulting firm that tackled global environmental issues, countering with smart, scalable and relevant projects. He believed that incorporating innovative, resilient and sustainable techniques into clients’ projects would help reduce our carbon footprint and the long-term effects of climate change — one of the defining issues of our time. What began as a sole proprietorship evolved into a collaborative and interdisciplinary team of talented landscape architects, architectural/urban designers, planners and technical staff.
In 2019, These two firms came together as Nadi Group: Donald Westphal seeking the perfect complement to transition his extensive land planning legacy and Emeka Nnadi seeking a kindred  practice that would help extend innovation in masterplanning, landscape architecture and urban design across more of North America.

Now one studio with offices in Canada and the United States; Nadi Group has built a strong reputation and innovative body of work. The group has received industry and peer recognition, national and international design accolades for delivering thoughtful, creative and sustainable design solutions for a variety of projects and clients, and a strong culture of collaborative design. The studio is inspired by the United Nations’ 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals. Three of these goals (Clean Water and Sanitation; Affordable and Clean Energy; and Sustainable Cities and Communities) specifically inform our work.
We aspire to bring innovation to our clients’ projects, increasing holistic short and long-term value. We love to design, and we do it with a passion to design for a better world.
