Nader Khalili ,an Iran Architect who is also the founder of the California Institute of Earth Art and Architecture has died at the age of 71. He used to design tall buildings, but later he switched his focus to design for poor and houses to accomodate victims of disaster. 
“I decided I had enough. I closed the office, bought a motorcycle, and went into the desert to work with the people on their ideas and dreams” Nader Khalili, 2005
"Superadobe: The technique uses long snake-like sand bags to form a beehive shaped compressive structure that employs arches, domes, and vaults to create single and double-curvature shell structures that are strong and aesthetically pleasing. "(source: Wikipedia)
According to Nader Khalili,five unskilled workers can build a two-person superadobe in less than one day. The architect believed that the sandbag is the fastest, convenient, and cheapest materials to help the victims who lost their homes to built a house. Superadobe become popular in Iran, Iraq as refugees shelters.
The construction method is simple: filing long sandbag with earth and stack them in circular plan. Barbed wire is laid between courses to prevent the sandbags from shifting and to provide earthquake resistance.
"The system employs the timeless forms of arches, domes and vaults to create single and double-curvature shell structures that are both strong and aesthetically pleasing. While these load-bearing or compression forms refer to the ancient mudbrick architecture of the Middle East, the use of barbed wire as a tensile element alludes to the portable tensile structures of nomadic cultures. The result is an extremely safe structure. " (source: earthbagbuilding)
