A hallmark of folk architecture is that it "fits in" with the surrounding physical and cultural environment. Like ballads and baskets, folk houses vary according to regional and ethnic configurations, and express a personally meaningful style.

Many students of architecture are drawn by the functional and inventive ways that people have traditionally coped with the details of survival. People in different regions have developed ways of taking advantage of natural energy sources and the landscape's innate character to find comfort. Climate and locally available building materials affect house design and construction. The same style of house may be made of heavy, hewn, oak logs tightly chinked and sealed in horizontal weatherboarding in the cold climes of Missouri or Indiana, but it might be built of light pine poles and left unchinked and cool in Georgia or Mississippi.
