The roof of the Bijenkorf is normally a gravel roof. LOLA Landscape Architects In the design for the greenery on this roof, we've shown how nature is slowly making its way through the gravel, permanently establishing a place on the roof. Because that's what we want most, of course: permanent greenery. The greenery was provided by Ebben Tree Nursery en The City Nursery of the municipality of Rotterdam. It was constructed by Dark green.
