Christopher Alexander and his associates, with the participation of future users, realized their largest project based on a specific "Project Language" on the periphery of Tokyo: the Eishin Campus, now a private high school for 1,000 students. In this book, authors from European and Japanese cultural spheres address the development process and the (inter)cultural dimension of the Eishin Campus. Further contributions examine the timeliness and relevance of Alexander's theories in architecture and urban planning.
