Book excerpt: Public Natures: Evolutionary Infrastructures explores the potential to shape a new public realm. Essays, roundtable discussions, and selected projects by WEISS/MANFREDI identify new terms, conditions, and models that insist architecture must evolve to create more productive connections between landscape, infrastructure, and urban territories. With a foreword by Barry Bergdoll and contributions from Kenneth Frampton, Preston Scott Cohen, Felipe Correa, Keller Easterling, Paul Lewis, Hashim Sarkis, and Nader Tehrani, Public Natures is both monograph and projective manifesto and suggests a new paradigm for infrastructure that is distinctly public in nature.
