Bali is not only rich in culture and art, but also in the field of housing and architecture, especially traditional houses. Apart from functioning as a place to live, Balinese people build their traditional houses with a rule called Asta Kosala Kosali, namely the rules for laying out rooms and buildings like Fengshui in Chinese culture. Like Fengshui, Asta Kosala Kosali also regulates the procedures, layouts, and building layouts for houses or places of worship based on the Nine Rulers (Nawa Sanga) in each corner of the wind with Lord Shiva as the focal point.
If we look into it, in general, the architecture of this traditional Balinese house is always filled with decorations such as statues. The Balinese produce their own various equipment which is also used for their religious rituals. In addition, the Asta Kosala Kosali spatial concept is based on eight things, namely the balance of the cosmos between humans, nature and the creator, hierarchy of values, cardinal directions, open space, proportion and spatial scale, chronology and development processions, the honesty of structure and honesty in using the material.
Uniquely, the dimensions of the house measurements do not use the meter, but the anatomical rules of the body such as the hands, fingers, arms, and legs of the house owner. Then assisted by the undagi as a pedande or holy person who has the authority to help build a house or temple, so that it is believed to create a proportional space and bond between the owner and the building of the house. Laying the building is for convenience and safety. Balinese architecture has unique characteristics using ancient culture and art in every element of its architectural design. In addition, this design is heavily influenced by Balinese Hindu traditions and a touch of ancient Javanese elements. Land according to the Asta Kosala Kosali tradition which is suitable for the location of housing construction is cultivated land that is sloping to the east or sloping to the north. In addition to the location of the soil, the soil texture must also be ensured of good quality. The soil is reddish and has no smell, including the type of soil that is good for living in.
Not only land but in Asta Kosala Kosali the type of wood also has an important role in development. Such as sandalwood which is good for the roof of a house, suren wood for the walls, teak wood which is suitable for a bed (bale), and there are many kinds of wood that have their own meaning.
After being arranged according to the Asta Kosala Kosali tradition, a building that is located in the east will be made, the floor is higher because according to the beliefs of the people of southern Bali, the eastern part is considered as the upstream or part of the head that is consecrated. Meanwhile, according to Feng Shui, the position of such a building has a positive effect. A suitable building to be placed in the eastern part is a family holy place which in Balinese is called merajan or denial. Meanwhile, the kitchen is located in the southwest, calculated from the left side of the entrance to the house area, because according to the Asta Kosala Kosali concept, this place is the location of the God of Fire. In addition, the unique thing that needs to be known from the Asta Kosala Kosali tradition is that a building architecture should not exceed a coconut tree height of approximately 15 meters. Until now, Balinese architectural art with this tradition continues to develop following the developments of the present era.
