Shacks are small, temporary dwellings that can be found in many different places around the world. The term 'shacks' can refer to both HUTS and leantos. HUTS are typically made of natural materials such as wood, straw, or mud, and are often used as a shelter for nomadic people. Leantos are similar to HUTS, but they are usually built on stilts and have a sloping roof. Both HUTS and leantos are commonly used as temporary dwellings, and can be found in rural areas, forests, and even on beaches.
