Stilt houses are made from wood, bamboo, cane, or rattan. A traditional stilt house typically has an area for drying rice, set one or two steps below the main level. The area under the house is either unused or used as a pen for livestock.
Tay and Nung people in northwestern Vietnam (including Lang Son and Cao Bang) typically build their stilt houses up against a slope. Ideally, the front of the house should overlook fields; close views of mountains, rivers and forests are avoided. The Tay and Nung believe that a mountain peak is like an arrow, which, if pointed at a house, might injure its residents. Trees, meanwhile, are associated with fierce beasts, and thought to bring bad luck to livestock. Nearby streams are thought to cause money to flow away from a house.
