Rotterdam roof park: A multifunctional structure of shared use : Defining four spatial dimensions of multifunctionality

In the context of urban planning, concepts of multiple land-use refer to situations were the existing space is more intensively used (Habiforum, cited in Hooimeijer et al, 2001). This can be achieved by morphological integration of functions (stacking of multiple functions in one building or construction), by mixed space use (multiple functions in a certain defined area) and by temporal shared-use of the same space.
