On various floors, roofs have been designed as roof gardens. Most of them are viewing gardens. They consist of a composition of low green areas (mainly sedum species) and gravel. On the side of the main entrance, containers with higher plants have been added. Loose shrub willows and tight trimmed privet hedges are visible from the street.

Only one roof adjacent to the staff restaurant is accessible. On the natural stone floor, loosely strewn, are reddish-brown steel containers with trees that will form a canopy. The currant trees break the high facade walls and provide shelter from the wind. Spotlights have been placed in the tiles in a pattern of constellations, like an inverted starry sky under the treetops.
