The landscape architecture world lost an influential voice recently with the passing of Robin Mack Key — a talented designer, preservationist, and steward of some of New York’s most meaningful cultural landscapes. Robin was also an extended member of the DeepRoot family: she was the sister-in-law of DeepRoot Vice President Al Key, cofounder of the Silva Cell. As we remember her life and work, we join many across the industry and beyond in recognizing an impressive career.

As founder of RKLA Studio in Manhattan, Robin built a respected practice known for its work across historic preservation, cultural institutions, educational campuses, public spaces, and residential landscapes. Her portfolio included notable New York-area landmarks such as Saint Patrick’s Cathedral, Tavern on the Green in Central Park, Storm King Art Center, The Noguchi Museum, The Olana Partnership, and Serviam Gardens in the Bronx. Among her most significant projects was the restoration of the landscape surrounding Saint Patrick’s Cathedral, a project she described as a “meaningful gift” back to the city she loved.

One of the most high-profile projects completed by Robin Key and her RKLA Firm, the restoration of Saint Patrick’s Cathedral Complex, included new Hornbeam trees, bluestone walkways, and the integration of the site’s geothermal infrastructure.

Robin’s work was defined by horticultural knowledge and a deep respect for the cultural and physical history of each place. The Cultural Landscape Foundation remembered her as a designer who bridged historic precedent and contemporary design, with an approach grounded in sustainability, maintainability, and stewardship. In 2018, she was elevated to the American Society of Landscape Architects Council of Fellows in recognition of her contributions to the profession and to cultural landscape stewardship. Beyond her built work, she served on the Stewardship Council of The Cultural Landscape Foundation, co-chaired the board of The Olana Partnership, and served on the board of The Noguchi Museum, extending her influence through advocacy, mentorship, and public service.

For those of us at DeepRoot, Robin’s career is especially meaningful. Her work reflected many of the values we hold close: respect for living landscapes, long-term stewardship, thoughtful collaboration, and the belief that well-designed outdoor spaces can make cities more resilient and connected. And to Al Key and his family, we extend our sympathy, as well as to Robin’s husband David and their family. Many people were shaped by her enduring commitment to the landscape architecture profession.
