Adobe houses are traditional dwellings made from a mixture of clay, sand, and straw, which is shaped into bricks and dried in the sun. This building method has been used for thousands of years, particularly in arid regions where these materials are abundant. The thick walls of adobe provide excellent insulation, keeping homes cool in the summer and warm in the winter. These houses are often associated with the Southwestern United States and Mesoamerican cultures, where they were commonly built by indigenous peoples. Today, adobe construction is appreciated for its sustainability and energy efficiency, making it a popular choice for eco-friendly homes.
