Hoerr Schaudt, in collaboration with PLANT Architect, Inc., STIP, and Adrian Blackwell, won an international competition to revitalize Nathan Phillips Square in Toronto, Canada. Phase I of the project was the design of Canada’s largest publicly-accessible green roof, which transforms the wind-swept podium of city hall into a verdant urban park. The planting design of the green roof responds specifically to Toronto’s harsh climate using deeper soil profiles to allow grasses and native perennials to thrive. These plants provide height, an important design element within such a vast garden, as well as winter texture and seasonal color that shifts with the changing seasons. The next phase of the redevelopment focuses on the open square adjacent to City Hall and is underway.
