Architecture now returns to a search for its roots as a profession normally focus on ways to reduce unnecessary elements to enhance the essential of spaces. Many other modes of thought think architecture is the sense that returns to its roots is a search for an authentic basis for design thought. The primal elements, such as blocks, planes, cubes and what not are thought to be most necessary and important things for ideas of human habitation to emerge. Therefore, those primal elements form the elemental foundation for all subsequent elaboration of thought.
The German Pavilion was designed by Ludwig Mies van der rohe for the international exposition in Barcelona, represents architect's attempt to reduce the constructions to simple and complex elemental principles.
This building contains two horizontal planes which creates a space in between that is high enough for human beings. one is floor, parallel to the second planes with the similar principle. And the other one is overhead. Those two planes held apart by two rows of columns and each four of them develop three spaces instead of dividing only one space between pairs of columns. This arrangement of spaces might stimulate architectural ideas such as proportion, side, and front that developed from the patterns of columns placement. The placement of columns and two planes in between horizontal space differentiate the human area and sky, creating more interesting spaces by arranging it differently. So it can tell the primal elements are related to the spatial organization or based to it.
Those vertical planes that are placed in The German Pavilion as walls, which are designed to separate domains. The outermost of these walls contain not the building but does define the site within their confines. And those walls let the natural landscape to be absorbed by the building within the wall without even move one tree. Therefore, a good design can use the natural element to enhance the
