This tower project has a floor area of 54,859㎡, with commercial, cultural, and community spaces on the lower levels, and officetels on floors 5 through 27. To ensure the maximum building footprint ratio (40%) as well as optimal natural light conditions, a C-shaped plan is extruded into a 27-story tower consistent with the Domino Matrix to reach a height of 100 meters, the maximum height allowed by law. When the C-shaped plan is simply repeated vertically, however, the floor space of the entire tower exceeds the legally allowed amount by approximately 10%. To reduce this mass systematically, missing matrices are introduced, meeting the maximum FAR (970%) throughout the building mass. Through 15 missing spaces, the building gains more exterior surface and corners for more natural light and better views. The spaces created by the missing matrices are landscaped with trees that are visible from the inside and outside of the building. Inside the tower, a total of 49 different types of units, 172 units in total, are arranged heterogeneously to reflect and exploit rich spatial conditions. For example, in the area created by the 15 missing matrices, there are 40 units with bridges that divide public (living/dining area) and private spaces (bedroom) within individual units, along with 22 units with gardens.
