Optima Roof Greening of Germany is responsible for the extensive greenroofs shown below on the corporate office building of VHV in downtown Hannover, Germany. The landscape architect who designed the planting plan is Uwe Isterling, BDLA. The photo illustrates how colorful and creative designs can be incorporated into large surface areas (3,275 m²). The reflective qualities of the adjoining building add to the design interest.
The plants include various grasses, sedums and herbs set into 6 cm of Optima-light extensive substrate.
