Marion Weiss characterizes one of the motivations behind the work of Weiss/Manfredi as frustration with the boundaries between architecture, landscape, infrastructure and urbanism. She contrasts closed, “perfect” circles of fortified cities past and present, with open-ended, multivalent architectural interventions in urban space and site condition. Weiss describes projects by Weiss/Manfredi that stress synthesis, infrastructure and networked occasions, from the Olympic Sculpture Park in Seattle, to recent and forthcoming projects such as the Bridge at Cornell NYC Tech, Roosevelt Island, and the Sylvan Theater at the Washington Monument.
