Berlin's real estate market is still booming, neighborhoods are "developed", people are forced out of their living environments. Residential, work and commercial spaces become investments for real estate corporations, trust funds, and anonymous owners, while a politicized tenants' movement demands the right to the city for all. But who are the real players behind the eco­nomic exploitation of urban space? What allows them to act the way they do – and how can their actions be politically and societally monitored, controlled, and thwarted? X Properties examines the impact of financial capital on the social and cultural production of the city, its forms of relationality and subjectivity. The book is published on the occasion of the homonymous research and event project at neue Gesellschaft für bildende Kunst (nGbK). It combines case studies from Berlin with global perspectives on the de-/financialization of the city.
