This paper describes that how all architectural elements are classified and represented with the human recognition methods such as extension, attribute and intension from the stand point of cognitive science, and then considers relations between representation of architectural elements and their shape, definition of their existence in the space, and dynamism of architectural design process. For design synthesis, knowledge-based model of design is needed which has the structure in the framework for representing knowledge, and we proposed the prototype of architectural integrated fneta-model in the object-oriented paradigm. In this model, all architectural elements are represented with above classification rules, and many design processes can be formalized as human desingers do.
