There are 3 types of southern stilt houses, RUEN KHRUENG PHOOK (Meeting house with rope),[9] plank house and masonry house. The defining characteristics of the stilt houses of the southern region are the structure of the roof and the stilts on cement poles. The weather of the south of Thailand always rainy with many typhoons, so the house must be stronger than in the other regions. The structure of the southern stilt house is also unique. The walls are made from layers of wood boards, the windows are narrow, using mortise and tension joint instead of the nails, and it has a lower gable roof than other regions. There are 3 roof styles that were influenced by other countries. Firstly, the gable roof follows the basic style. The tiles are made of grass, baked clay, or rhomboid tiles depend on the status of the owner. The roof will be decorated with carved wood if the owner is of high status. The second style, PANYA or LIMA roof was influenced by Indonesian and Malaysian design.[10] This roof is very strong against storms. The slopes of the roof are trapezoidal. The last type is a Brann’s roof or Manila roof . This roof was integrated from gable roof and PANYA roof. This roof is lower than the other type, the top part is a gable roof and the bottom part is a PANYA roof, the trapezoidal roof supports the top part. Many Muslims in the south of Thailand use Manila roof and the top of the roofs is decorated with a cylinder of carved wood.
