Mud-brick houses are structures made from natural materials, primarily mud and straw. These bricks are formed by mixing soil with water and then drying them in the sun. This building method is ancient and has been used in various cultures around the world, particularly in arid regions where wood and stone are scarce. The advantages of mud-brick houses include their excellent insulation properties, which help keep interiors cool in hot weather and warm in cooler months. Additionally, they are environmentally friendly, as they utilize local materials and require less energy to produce compared to conventional building materials like concrete or steel.
