The purpose of this study was to identify the planning characteristics of unit plan for the high-rise residential buildings in Korea. 5 high-rise residential buildings in Korea higher than 60-story were selected to represent the building plan types. They were analyzed primarily in terms of the shape of typical floor. The planning characteristics of unit plan were classified as unit combination, unit shape, composition of interior space, and exposure to outside. The results of this study were as follows; various kinds of unit combination appeared due to the use of non-symmetrical shape of typical floor plan, the variation of typical floor plan also effected on the shape of unit plan but it sometimes caused negative result, the role of LDK in unit plan increased as a center of family life which can dominate a good view, and in spite of the disadvantage on daylighting and air ventilation, each unit plan tried to compensate it with a fine view on different directions.
