Prairie and mid-century modern are both architectural styles, but they have distinct differences. Prairie style, popularized by Frank Lloyd Wright in the early 20th century, focuses on horizontal lines and integration with the landscape, with low pitched roofs and open floor plans. Mid-century modern, on the other hand, emerged in the mid-20th century and is characterized by simplicity, functionality, and integration of nature as well, but with a more minimalistic and sleek aesthetic, often using new materials and technologies of the post-war era.
