The purpose of this study is to provide the basic guideline of the archite-ctural planning and design of the women`s hospital for optimizing the area compostion and spatial allcoation. The method of this study is to investigate and analyze the functional spatial composition based on the area composition and spatial allocation of the 4 departments space in women`s hospital through a analysis of 9 cases study. Data collecting skills such as drawing documents analysis, field survey and observation were used to examine of the present facility condition. Hence this research is to grasp the present condition of department of the women`s hospital, to inquire the area composition and spatial allocation. Finally, The derived important factors are expected to use as the basic data at the time 4 planning for the space programing of design women`s hospital.
