This essay discusses the problem of design and the challenge for architects to address the dimensions of design in the architecture of a building. The problem of design encompasses many interweaved dimensions at several levels: the level of morality, the level of aesthetics, and the level of pragmatic function. The dimensions of the problem include attention to proximal space, critical perspective of conventional design, communication of truth, and learning how to see. The essay presents functionalism of the modern movement as an example of dealing with the design problematic. The solutions of modern architects such as Le Corbusier and Frank Lloyd Wright are discussed as a beacon for architects undertaking the challenge of design without delimiting its dimensional complexity.
