The basic concept assumes that the artificially created spatiality of the courtyards and roof areas will be filled like vials for experiments with biological materials: This is conceived as low-maintenance and for everyday use. The choice of plants is based on a biotope formulated by rainwater and retaining technology. Against this background, bog plants that are suitable for the Bremerhaven location particularly found use: Ericaceae, calluna and rhododendrons thematically accompany the inner courtyards.
