Architecture is changing rapidly with contact of various cultures and development of modern technology and it is also becoming Polycentric. We can look at the tendency of deconstruction that denies logical rationality of modernism and minimalism that is known as a vertex of modernism. This kind of flow appears to be one of tendencies of interior design. Therefore, to satisfy the residents with the interior design, our study proposes a better space improving monotonousness of the existing apartment through case study. Through the case study, if we analyze the tendency applied to the characteristics of minimalism, we can divide into shape and space. Minimalism space says that the resident can build his/her own space according to the characteristics of the object. Also, it has an advantage of the resident being able to bring in furniture or decoration to change the characteristics of the space. With more accurate understanding and borrowing, we should do multilateral study to research the mixed loading and uncertain minimalism through the case study of apartment space.
