Horizon Hall, a soaring 218,000-square-foot academic and research facility at George Mason University, is the new home of the university’s College of Humanities & Social Sciences. The campus’s largest building houses classrooms, faculty spaces, spaces for study and reflection, and the Mason Innovation Exchange (The M.I.X), an interdisciplinary center where inventors, artisans, and entrepreneurs can create projects, exchange ideas, and find support to foster product development.
