This study re-composes the collective architectural criticisms of Jeffrey Kipnis, who sees deconstruction neither as a new formal vocabulary nor "the re-value of all things" but force that re-formulate the relationship between the discourse and design in architecture. The issue of "undecidability" is proliferated from re-composing the very first critical essay of Kipnis. From this issue of "undecidability", this study, by using metaphors appear in the essays of Kipnis such as "chora" and "the separatrix", explores further towards the possibility of articulating "boundary as a decision making frame" which is the condition of recognizing object. At last, one last metaphor, "the fetish," as a mechanism of boundary articulation is unfolded. Throughout the dis-couse of this study, two main issues are proliferated. First, the relationship between the discourse and design in architecture is re-formulated. Second, the relationship between architecture and the notion of boundary is suspended.
