Mud-brick buildings are structures made from a mixture of mud, straw, and water, which is shaped into bricks and dried in the sun. This traditional building method has been used for thousands of years, particularly in regions with hot, dry climates. The bricks are known for their excellent insulation properties, helping to keep interiors cool during the day and warm at night. These buildings are often found in ancient cities and rural areas around the world, including places like Mesopotamia and North Africa. Mud-brick construction is sustainable and environmentally friendly, as it utilizes locally available materials and requires minimal energy for production.
