This vegetable green roof garden designed as an outdoor classroom adds an unusual dimension to traditional green roof design. A full-time gardener utilizes a planting system custom-designed by Hoerr Schaudt to teach inner-city youth methods in gardening. The garden maximizes two heat sources, ambient heat from the building and solar energy, which allows for gardening nearly all year.  Soil depths of nearly a foot allow for a wide variety of plant material.
