One of the most famous traditional house of the people of the Riau Islands is the "Belah Bubung" traditional house. This house is also known as the "Rabung" house or the "Bumbung Melayu" house. The name "Belah Bubung" was given by the Malays because the shape of the roof was split. The size of the house built is determined by the ability of its owner, the richer a person is, the bigger the house and the more variety of decoration. However, wealth is not an absolute determinant. The most important consideration in making a home is harmony with the owner. To determine whether or not a house is compatible, the owner calculates the size of the house by cubits, from one to five. The veins are: snake swimming, pursuing ripples, ripples climbing beetles shelter, debt out of debt changed debt, and five debt has not been affected. The best measure is if it is right on the count of ripples to climb the shade beetle.
