The Pueblo Indians lived in cliff dwellings carved into cliffs and mountains in the American Southwest. These multi-level homes were stacked on top of each other to maximize space in small areas. Seminole Indians in Florida built chickee homes on stilts above the ground and with slanted roofs to stay dry in the damp climate. Navajo tribes constructed hogans, which were round structures made of wood and compacted earth that insulated inhabitants and kept them warm.
