This book unpacks the process of financialization in the planning of urban mega-projects. On one hand, it explores the literature on real estate finance within the context of planning; on the other, it showcases two case studies to explain how the financialization of urban mega-projects operates. By framing urban mega-projects, real estate, and financialization trajectories, the book examines unconventional planning and real estate concepts nowadays affecting urban studies. Conceptualizations of urban mega-projects, planning tools, as well as real estate markets, assets, and funds are widely described. Moreover, the case comparative analysis of the property financialization and spatial planning of Amsterdam South Axis and Milano Innovation District provides evidence-based and usable knowledge for both scholars and practitioners, by illustrating aspects of plan-making, decision-making and business strategies usually unknown in the field of urban policy analysis.
