"Usonian" refers to a design philosophy and architectural style developed by the American architect Frank Lloyd Wright in the 1930s. It emphasizes simplicity, functionality, and harmony with the surrounding environment. Usonian homes are typically single-story structures that feature open floor plans, large windows, and natural materials, promoting a connection between indoor and outdoor spaces. The term "Usonian" is derived from "United States of North America," reflecting Wright's vision of creating affordable, uniquely American homes for the middle class. These designs often include built-in furniture and carports, aiming to provide a sense of community and a sustainable lifestyle.
