Aztec House

Houses in the New World displayed varying styles, from the Cape-style houses of New England to the claim shanties in the West to the ranch houses of Texas and Mexico. Often the house style reflected the cultural heritage of the people who settled the land. For life in their relatively dry climate, the Aztec built their homes as simple structures made from adobe (a mixture of water and dirt), with a thatched roof.
