As students in architecture, we usually struggle to make a efficient diagram showing things such as concept, process and analysis. And when I think of the feature of diagram, the visual character of diagram is simplity. To me, it means the diagram is abstract tool to represent the idea and the process of design. But Stan Allen defines the diagram as the organization, “description of potential relationships among elements, not only an abstract model of the way things behave in the world but a map of possible worlds.” And these possible worlds became full of invisible images and information opposing to materiality of buildings. In this invisible time, the diagram has potential to be efficient method as well as strong tool in architecture because “a diagrammatic practice locates itself between the actual and the virtual”. I have been persuaded by Stan Allen to here.

Next, the diagram architecture is… “ a diagram architecture is an architecture that behaves like a diagram”. Like diagram, architecture confronts the period of immateriality and invisibility. And Stan Allen insists that a diagram architecture produces complex performative effects with a unfixed architectural envelope and is located in the architecture’ place in 21th-century. In my opinion, architecture is basically including human behavior and providing the place for human activity. In spite of the character of new century as information and images, I wonder how architecture integrates between fundamental function of architecture and immateriality of this period. Could diagram architecture is one of method for this?
