Book excerpt: New Investigations in Collective Form presents a group of design experiments by the design-research office THE OPEN WORKSHOP, that test how architecture can empower the diverse voices that make up the public realm and the environments in which they exist. Today, society continues to face urban challenges--from economic inequality to a progressively fragile natural environment--that, in order to be addressed, require us to come together in a moment when what we collectively value is increasingly difficult to locate. Organized into five themes for producing collectivity--Frameworks, Articulated Surfaces, the Living Archive, Re-Wiring States, and Commoning--the projects straddle the fine line between the individual and collective, informal, and formal, choice and control, impermanent and permanent.
