Most of Malay houses are built as Rumah Panggung (lit: "stage house") houses built on stilts. The main characteristic of a typical Malay kampunghouse is its on stilts or piles. This was to avoid wild animals and floods, to deter thieves, and for added ventilation. In Sumatra, traditionally stilted houses are designed to avoid dangerous wild animals, such as snakes and tigers. While in areas located close to big rivers of Sumatra and Borneo, the stilts help to elevated house above flood surface. In parts of Sabah, the number of dowry buffaloes could even depend on the number of stilts there are in the bridal family's home.
The traditional Malay house require stairs to reach the elevated interior. Usually the stairs connected the land front of the house to the serambi (porchor verandah). Additional stairs might be found on back of the house. The stairs can be made of wood or brick structure covered with tiles. For example, in Melaka and Riau the staircase is always decoratively moulded and colourfully tiled.
The roof of traditional Malay houses are designed to provide shade and protection from heat and rain, as well as to provide ventilation. The basic design of a roof on a Malay house is gabled roof, an extended frame with ornaments on the edges of the roof. The vernacular Malay roof is best suited for hot and humid tropical climates. An example of the gabled roof can be found in the design of Rumah Lipat Kajang. However a pyramidal styled pitched roof can also be found on houses such as the Palembang Rumah Limas.
In Riau and Jambi there are several different styles, especially of the roof design. The Rumah Lancang or Rumah Lontik have curved roof with boat-like structure on stilts.[2] The design somehow similar to Minang Rumah Gadang. The Rumah Lipat Kajang have flat roof structure with crossing edges forming "x" pinnacle on corners of the roof. The larger structure with similar crossed corner roof is called Rumah Limas. This type of roof and structure often used in palaces of Malay kings as well as government buildings. The Rumah Limas is also known as the traditional house of South Sumatra and Sundanese West Java, although they have same "Rumah Limas" name, the design is slightly different. The modern government and public buildings often based on Malay style roof design, such as government buildings in Riau and Jambi, as well as the roof design of Muzium Negara in Kuala Lumpur.
