Public space has become a widespread agenda for architects. The „space between the architecture“ has become subject to political correctness. Yet the notion of public space goes far beyond generous gestures in the built environments. In a global market economy, the public extends to geopolitics in planetary scale, yet very few spatial factors have been subject to environmental thinking as a public domain. With policies like the Paris Agreement, the first steps have been made in understanding the potential of a global public space, yet spatial practitioners stand far from being at the core of these debates, while their tools of projecting scenarios can potentially be the most effective in animating future developments.
