The beauty of architecture [is that it] can promote interaction and create the possibility for collaboration without getting administrative approval. Even though academic departments are often insular, both physically within their building and practically in their academics, students are still free to move about a campus after all. … I can imagine two types of these spaces. The first is a space where people of different disciplines do independent work in close proximity to one another, much like an undergraduate Building 20. Basically, put people in one space and let the proximity do the work. The second is a space much like the d.school, where students gather to work together on tasks inspired by the world, not by a discipline. One puts students together, the other one invites them.
