Since 2006, we can see the dome houses in the area called Ngelepen, which belongs to the village called Sumberharjo, the district of Prambanan, the province of Yogyakarta, Indonesia. These dome houses which are round in hape are the donation from the World Association of Non-governmental Organization (WANGO) and Domes for the World Foundation (DFTW) for earthquake victims in whose houses were destroyed by the earthquake on May 27, 2006.
In addition to the unique shape, the dome house also has many advantages. One of them is that the Dome house is resistant of earthquake. Because, in the structure of the dome house has no corners and junctions which are very prone to cause wreckage when hit by an earthquake. Since there is no connection at dome home, which is the weak point of the building when it is rocked by an earthquake, the dome house constitutes the house which is resistant for earthquake. According to the architect, the dome house is also able to withstand the wind of 450 km / h, and is durable for centuries.
Dome homes are designed around a semicircle. The building is made using the mold (airform) shaped like a balloon and the upper part be filled with cement concrete. The Burden on the wall of the dome house is also shared equally on each side of the foundation. The foundation is not very deep: only about 20 cm, so the foundation is not easily broken.
In addition, The steel webbing is installed in the middle of the floor to make the dome house safe when earthquake. In the box home, when an earthquake happens the walls will attract each other and the connections can be broken to cause the walls and the roof collapses.
The shape of dome house is much different from The house owned by Indonesian people. The dome house is like the igloo house, owned by Eskimo tribes. The unusual shapes of these house make people interested in visiting this village to see the dome houses. Now this village becomes the tourism destination which is popular in Yogyakarta.
