Nhà sàn is a traditional stilt house commonly found in rural areas of Vietnam and other Southeast Asian countries. These houses are elevated above the ground, typically supported by wooden pillars, which helps protect against flooding and pests. The design allows for better ventilation and keeps the living space cooler in hot weather. The structure of a nhà sàn often reflects the local culture and lifestyle. Many ethnic minorities in Vietnam use these houses for both living and storage, with the space underneath often utilized for animals or tools. The materials used are usually wood, bamboo, and thatch, showcasing sustainable building practices.
