I believe that all the design process can be classified in some guideline. These guideline have different request which support and enhance the meaning of concept. After 4 years study of architecture, I figured out that maybe the strongest design always based on most strictly principles. So, what is these principles? In my opinion, that would be matter, space and structure which can be combined as architectural design. First, matter, not only as a object but also mention the material and the characters. Furthermore, the type of a space can represent the quality and identity. Finally, the structure as a infrastructure and framework can support the whole design. The concept should be based on one guideline as the main idea.
