The Joglo house is a traditional Central Java building, generally the joglo house is made of teak wood. This building is also often used as a pavilion. In the building structure, the roof of the joglo house is supported by the main pillar called the Soko Guru, which consists of 4 poles. The philosophy of these 4 poles is a symbol of the influence of the forces of the 4 cardinal directions. This building uses the method of hooking the joints between logs in its construction.
The main structure of the joglo house has a rongrongan structure, which consists of:
1. Umpak is the foundation of the joglo house building.
2. Soko Guru is the 4 main pillars in the middle of the building.
3. Plumbing is a stabilizer to withstand the pile construction from shocks.
4. Sunduk Kili is part of the fastener to lock the joint hooks of wooden beams and poles.
5. The drag is a beam connecting the ends of the poles on the joglo house frame which is linked to the blandar, this section also has a stabilizing function.
6. Blandar is a term for wooden blocks.
These six main structures will support a structure called an intercropping. Tumpangsari itself is formed with an arrangement of blocks that form a pyramid. Tumpangsari has 2 parts consisting of Elen and Elar.
a. The elen is placed in a circle in the sledge beam. Serves as a roof supporting ceiling structure that sticks up like a hill. Elen will be an odd number of between five, seven or nine.
b. Elar is placed in a circle outside of the rodent beam. Serves as a support for the usuk and the edge of the roof structure. Has an odd number of between three or five.
