Crude shelters are temporary dwellings that are often constructed with limited resources. The term 'crude shelters' can refer to SHANTIES (8 letters), HUTS (4 letters), and leantos (7 letters). SHANTIES are typically made of scrap materials such as wood, cardboard, and plastic, while HUTS are usually made of mud, sticks, and grass. Leantos are similar to HUTS but are more open and have a slanted roof. All three types of crude shelters provide basic shelter from the elements, but they are not suitable for long-term living.
