The shortage of available land in densified metropolitan cities demands maximizing its utility. Public authorities are required to find creative solutions to satisfy the growing demand for the supply of public space. The allocation of public services in privately owned buildings constitutes one instrument to answer these challenges. This conference introduced this tool by looking at the phenomenon of Vertical Allocations; specifically we examined how municipalities in Israel appropriate floorspace in newly built multi-purpose structures, which are privately owned. While designating these floors for public use, such as schools and kindergartens, municipal bodies assume responsibility for these new public resources. The conference focused on Vertical Allocation as presenting special challenges, among which are uncertainty and challenges from joint ownership ; too flexible or unknown future public functions ; potential friction and nuisances due to proximity of uses ; disagreement over construction costs and complexity of management within mixed-use buildings. The dynamic circumstances and challenges surrounding Israel’s implementation of Vertical Allocations and its integration of mixed uses can serve as a teaching model and a test case for the rest of the world.
