Andres Duany and Elizabeth Plater-Zyberk are credited with designing Seaside, which marked the beginning of the New Urbanism movement. New Urbanism is an urban design movement that emphasizes walkability, mixed-use development, and traditional neighborhood design principles. Seaside, located in Florida, became a model for other communities and inspired the development of many other New Urbanist projects. Duany and Plater-Zyberk's design of Seaside incorporated elements such as narrow streets, front porches, and a town center, creating a pedestrian-friendly and socially vibrant community.
