Architecture, like art, becomes iconic when it breaks from the current mode and challenges viewers and inhabitants to approach living with a new consciousness. Modernist houses introduced a new way to live with open floor plans and clean, modular designs free of unnecessary ornament ,Modern architecture is architecture of simple forms (rectangles) enclosed with flat opaque (solid) or transparent (glass) walls. The new materials – glass and steel changed the look of buildings, the experience of being inside looking out, and construction time and technique.
