Several factors such as rationalism, the development of science, the development of philosophy, and especially the development of technology caused the development of modernism. The use of the manifestations of technology, including the use of metal in building construction, began. The need to use metal structures and the use of glass in Chicago buildings and the formation of the Chicago School in 1871 and the construction of the Eiffel Tower provided a suitable basis for the use of new materials. After the World War, the need to build buildings using modern architecture was formed. Mies Vandervoort and Corbusier were famous architects of the sublime era. Le Corbusier considered the five principles such as elevation, roof garden, free plan, the use of extended windows, open view, and the use of cantilevered roof as the principles of modern architecture.
