Architecture encompasses the making and study of the buildings and environments that we inhabit. The concerns of architecture involve a wide variety of areas of study, including the art of representing built projects through drawings and computer graphics; the technology of building structure, building materials, and natural and mechanical systems; the history, theory, and art of making, using, and understanding buildings as cultural artifacts for human use; and the practice of architecture in the context of sustainable environmental systems, urban form, and business economics. The School of Architecture offers one accredited professional degree, the Master of Architecture (M.Arch.), and a non-professional research degree, the Master of Science (M.S.) in architecture, with four potential tracks: heritage conservation and preservation, metropolitan design, research practices, and sustainable design.
