Crude dwellings are basic structures that provide shelter and are often found in impoverished areas. SHACKS, SHANTIES, and HUTS are all examples of crude dwellings. SHACKS are small, often temporary structures made from wood or other materials. SHANTIES are similar to SHACKS but are usually more flimsy and constructed from scrap materials. HUTS are small, primitive dwellings made from natural materials such as mud, sticks, and grass.
