Architecture is equated by many with the material, and much of architectural education is geared towards acquiring the skills and expertise in doing that. Architecture can be conceived of as giving form (material) to the formless (immaterial), and through form (material) achieving the formless (immaterial). This paper presents an experiential approach for grasping the immateriality of architecture. Three components of the experiential are described - sentient experience, people-in-place experience, and numinous experience. The hope is to raise consciousness of the immaterial and of the cultural and the sacred.
