In high seismic regions of the world, including Turkey, there are too many low-rise residential buildings made of rigid masonry walls or flexible moment-resistant frames with brittle masonry partitioning walls. During even moderate earthquakes, these buildings suffer heavy damages and brittle failures causing hundreds if not thousands of people to lose their lives and homes. Hence it is essential to build a house with lightweight materials that have an earthquake resistance with a proper safety. Recently in some countries such as USA, Italy, China and Turkey; a new building system called 3D wire panel building system use prefabricated lightweight panels to construct low-rise buildings up to three stories. The panels are fabricated from polystyrene, steel, and shotcrete concrete .The lightweight of these panels, easy handling, high construction speed, good heat insulation properties, in addition to their low cost by avoiding formwork and need for skilled workers make it an acceptable construction practice. In the literature, there is no enough information on the design rules of this new building system .This paper presents some hits on the design rules and some applications in Turkey such as construction of a factory, construction of a three story villa and construction of mosque domes.
