Resulting from the urban conditions of the site the open space is composed of three different zones: the urban terrace, the urban yard and the garden yard.
The terrain of the urban terrace is on a higher level than the Heinrich-Böll-Straße, adjoining it in the west, and serves as a connection between the western wing of the street neighbouring building and the inner houses. The terrace is structured by the intarsia created from planted bands and wooden decks. The linear roof element of the canopied bicycle parking areas, shielding the private gardens next to the building, corresponds with the access balconies of the building.
East of the urban terrace the lowered urban yard unfurls. A gravel surface with a grove of plane trees (Platanus x acerifolia) creates a Mediterranean atmosphere, an additional lawn area provides further habitual qualities. Here generous room for common activities is provided. A band of high growing ornamental grasses separates the adjacent private gardens from the public area.
The garden yard, designed as a 'play-scape', connects the different elevations of the adjoining green corridor and the surrounding buildings. Lawn terraces alternate with playgrounds and recreational areas for children. In North-South direction sprawls an loosely planted orchard. Retention zones, designed as swales, drain away the runoff water of the buildings roofs. In the North of the site the so-called 'Grabeland' is located, which can be compared with an allotment garden site. Here oval compartments, enclosed from hedges, can be used from residents as private garden plots.
