In this design, the external volume is a simple cube which is regulated by zoning and FAR requirements. The distinct part is the internal atrium space. It is composed by two cones, one of which rests on the ground level and rises up, and the other one drops in a reverse direction from the top intersecting into the first one. The intersection of the cones from opposite directions generates an atrium entity whose volume transitions from broad and open voids on the ground and the top floors, to a narrow space in the middle. This vertical sequence of opening, squeezing and opening again also mobilize the floor plans which are otherwise a result of identical stackings as vertical repetition. From bottom to top, the planar slices of those two cones are constantly changing. The void space shifts from an eccentric position on the ground floor to a central position on the top and creates diverse in-between situations in the middle. During this process, the space between the external boundary and the atrium on each floor interacts gradually with the successive development of these two cones. This succession generates diversity for room layouts of the hotel and other spaces for public programs such as conference and banquet hall. At the same time the internal spatial configuration is reflected upon the building facade. What is presented here is a dual vertical succession. One is the distinct way of stacking floors, which in this case, creates diverse vertical communications through the atrium space. The other one is the succession of user experience especially inside the atrium space where the stairs meander along the surface of those two cones, succeeding from bottom to top, while creating a continuous circulation as well as visual connections.
