BIG’s proposal, The BIG U, is rooted in the firm’s signature concepts of social infrastructure and hedonistic sustainability. It envisions a 10-mile protective system that encircles Manhattan, protecting the city from floods and storm water while simultaneously providing public realms specific to the needs of the city’s diverse communities. Bjarke Ingels states: “We asked ourselves: What if we could envision the resilience infrastructure for Lower Manhattan in a way that wouldn’t be like a wall between the city and the water, but rather a string of pearls of social and environmental amenities tailored to their specific neighborhoods, that also happens to shield their various communities from flooding. Social infrastructure understood as a big overall strategy rooted in the local communities.”
