Continuing and concluding the analysis of seven cases of creative, cultural/artistic practices for the design of urban spaces of possibilities from Hanover, Germany, this chapter discusses how the organizations, networks, and projects under scrutiny provide their participants with spaces for challenging experiences, spaces for indeterminacy, and spaces for experimentation. This chapter ends with an integration of the insights gained about the seven cases across Chapters 1, 3, and 5. This intermediary conclusive integration clarifies how imaginaries are both emplaced and place-making and how social creativity, experimentation, and imagination are mutually constituted in successfully functioning urban spaces of possibilities.
