Frank Lloyd Wright's conception of houses featuring open living spaces is best exemplified by the architectural style known as "Prairie Style." This style emphasized horizontal lines, integration with the surrounding landscape, and an open floor plan that allowed for fluid movement between spaces, reflecting a more organic and communal way of living. Wright sought to create harmony between the interior and exterior environments, breaking away from traditional compartmentalized room layouts.
