Diagram has been a useful visualization tool like as sketch, drawing, model, image and photo, etc. in order to show an archit’s concept during the Architectural design process. Also the architectural diagram had accepted the philosophical diagram concept to get over the modernism.
Especially, the ‘abstract machine’ of Gilles Deleuze verified that diagram is able to generate non-representations and this concept has been used as a formal instrument to generate non-representative architecture. Some of architects started to focus and accept the important function of diagram not only as a good visible description, but also as a good tool to finalize the shape of buildings.
Therfore, the purpose of this study is to verify the contemporary meaning and status of architectural diagram by analyzing six architects’ diagram - UN Studio, MVRDV, SANAA, Rem Koolhaas, Greg Lynn, NOX.
The criteria for selecting architects is the characteristic of architects and their writings. Before analyzing the type of diagram, it has been investigated the characteristic and strategy of design, and the subject project which is well described the process of designing the diagram has been selected and analyzed. And after analyzing the subject architects’ diagram, it is founded that there are three main ways - ‘abstract machine diagram’, ‘program diagram’ and ‘digital diagram’- to use the diagram according to each architects’ design strategy. Gilles Deleuze had focused the diagram as a generating force and a map which can proceed the project during generating architecture form.
It is described hereinafter why the diagram is essential recently.
Firstly, modern society has been networked, multiplexed and multiplexed tiered, so it is needed to find new tool to control complicated territory, traffic line and urban flows, therefore, the diagram is being focused as a new tool.
Secondly, the contemporary architecture after modernism has been impossible to describe by only through geometry since the contemporary architecture has reflected site, place, behavior, deed, context and so on. Therefore, the diagram is focused as a tool to uniform the unclear atmosphere, nonlinear system and irreversibility.
Thirdly, the diagram is focused as a tool to enable to describe topologie, decentralism which is hard to describe by analog method.
Finally, the diagram is essential for post-structuralism to reflect the transition, difference, generation to structure by adding the time which had been excluded for the structuralism.
Therefore, recent diagram is different from former ones and is one of the essential tool for architectural design process.
