“Underground homes have several advantages over homes built above the ground.
Underground homes, or earthen homes, have extreme benefits over above ground housing across the entire board. Some of these beneficial qualities include their ability to save space above ground, their extreme insulative properties which make them highly energy efficient, and their extremely durable structures.
Underground homes and earth-sheltered homes are among the most popular types of alternative homes. Almost everyone knows the earth will moderate the inside temperature and reduce energy costs. That’s why potato storage cellars are common. These structures will “assure the grower that potatoes will be held at the proper temperature from harvest time to shipping time, anywhere from March to May.” Of course, the same principle can be used to build energy efficient homes, storm shelters and rootcellars.
