Roof garden with a system: the Optigrün Garden Roof
Green roofs and roof terraces - green roofs with high ecological value
The GARDEN ROOF is a particularly versatile form of intensive green roof. The intensive roof structure can be designed with lawns, shrubs, ponds and in combination with our system accessories, such as planters and edge elements. There is virtually nothing on a roof garden that you can't find in a traditional garden.
This creates a variety of roof landscapes with terraces or gardens - green oases in the middle of the city that offer relaxation areas, promote biodiversity and are characterized by a particularly high ecological value, for a plus in quality of life in a green environment!
