CLUSTER’s Downtown Rooftops research falls within the context of CLUSTER’s broader research endeavor exploring the network of downtown Cairo’s passageways, back alleys, side streets and in-between spaces as an alternative framework for the development and revitalization of Downtown. It is premised on exploring the semi-public spaces of common in light of the increasing restrictions on practices in public space. Downtown Rooftops offers a close analysis in relation to their spatial, social, and legal dimensions as well as the factor of accessibility to these spaces. The studied scope constitutes a second level of the city where different patterns of lifestyle take place in parallel to the everyday life that one experience in the more familiar spaces. This study aims to assess the possibility of intervention in these rooftops, to create further alternative urban spaces.
