The book "Raumbeschleuniger" discusses the importance of spatial exploration and experimentation in architecture to address the limitations of the current dead-end state of architecture. The concept of the "Raumbeschleuniger" (engl. transl.: space accelerator) is introduced, challenging us to rethink the value of space in our lives, especially in the context of the COVID-19 pandemic's impact on public, private, and digital spaces. The book advocates for redefining public spaces as a place of coexistence and shared experiences through various interventions and design strategies, offering valuable insights into the transformative power of spatial interventions and their contribution to a collective manifesto of shared spaces.
