Revisiting a "Really Green" Roof

On a recent visit to the Olson Family Garden atop the St. Louis Children’s Hospital, Jim Konrad was amazed to see how much the project had matured over the last ten years.  Designed by EDAW and Mackey Mitchell in 2000, this award-winning rooftop garden on the 8th floor of St. Louis Children’s Hospital provides a natural haven in an unlikely setting.  The garden is designed to enhance the healing environment by providing a place for children and their families to connect with nature – away from hospital stress.  What did it take to create this oasis? Try 130 tons of rock; 150 tons of sand; 50 tons of soil; 7,500 plants and bulbs; 5,000 pieces of limestone; 135 cubic yards of concrete; 88 lights, 8 aluminum canopies;  1 2-ton granite waterball, several sculptures, a fountain and 1 pond with 3 waterfalls.  Quiet areas with recessed seating niches and sheltering trees encourage private conversation and contemplation in this place that has steadily become more beautiful over time.
