Beyond a design school, the Harvard Graduate School of Design (GSD) is an immersive environment--a dense atmosphere saturated with creative and intellectual activity. Platform 4 represents a selective sampling of agendas cultivated at the GSD during the last academic year, revealing a diverse mixture of projects, research, and events. Organized as a searchable database, this publication documents both site and situation at the GSD--it is an institutional index. While Platform 4 records research trajectories from the past year, it also has the capacity to set agendas for future work. By framing a set of issues and topics, Platform 4 focuses attention towards particular areas of interest, allowing individual work to build on and contribute to a larger body of disciplinary knowledge. In that sense, the themes within this book become projective, they provide frameworks for future inquiry.
