The study purpose focuses on clarifying the visibility characteristics in office building lobbies planned with single cores, providing analytical theories and suggesting architectural planning directions of the spaces. Visibility Graph Analysis, including the measurement of VGA Mean Depth, VGA Integration, VGA Entropy, Clustering Coefficient and Control, was used for
analysing fifteen office lobbies. The findings of the study follow: (1) The layout of space program components, especially the relative locational arrangement of each program space, is correlated with the visibility configuration of lobby spaces and users' cognitional environment. (2) Visual crossing-nodes were found at users' circulation paths in case that lobbies were planned
lineally with front & rear entrances and elevator halls. The junctions of users' circulations appeared at lobbies in case that the spaces were accessible from front entrances only and open visibility appeared at the common area adjacent to the main entrances. (3) The ratio of lobby area to total accessible area showed proportional relationship to the ratio of VGA Entropy
variation. The reduction of the lobby area increases visual concentration effect. Also in this research, architectural planning directions responding the analysis results of 5 layout types have been proposed.
