During the beginning of modern architecture, le Corbusier proclaims that the use of materials such as plate glass, steel, and reinforced concrete as well as the image of the industrial age, were the basis of all revolutionary change that he proposed. For Hassan fatty and many others in this movement, the space that could be created by using such technological advancement had social corrective potential, and honestly of expression in the use of technology was considered to be an essential prerequisite to a brighter future rather than believing in this, Fathy felt that human being, nature and architecture should coexist in harmonious balance. For him, architecture was a communal art, that should reflect the personal habits and traditions of a community rather than reforming them.
