In this paper, we would like to clarify the way of differentiation among the dwelling unit plans by their spatial configuration in super-highrise condominiums developed in Tokyo Metropolitan Area. In the former part, through the interview to the architects, we illustrate their understanding toward the livingroom-connected type, which is used as relatively compact units, and corridor-connected type, which is used as larger and more privacy-secured units, is structured. In the latter part, we analyze that the variation among the livingroom-connected, intermediate and corridor-connected type is used for the ordering of unit plans, and that the order of the three unit plan types form an axis of values. We also point out that there are a few patterns of strategic unit arrangement in an apartment building and discuss that the architects use the axis to fulfill the various request from their clients.
