1.1 S.P.O.R.T. S.P.O.R.T., it looks like a general name of moving activity here. However, S.P.O.R.T. is a combining word that represents 5 meanings, space, public, overlap, rotate and transformation in this word. Space is our environment and active place, it is the most important portion that I operate and create. Public is represent share (act with other), including time and space. Overlap means the stack of space that is not at the same level but is occurred in the vertical. It breaks the vertical boundaries of the upper and lower floors. Rotate is a dynamic process of exchange through the fixed center (core), which is the source of spatial variation. Transformation is forms and vision changes of building exterior and interior. Because of the rotating schedule, it presents diversification architecture not a rigid building.This is different from the past that our concept of using space. It is more efficient to use the extra space and rests.Because of the movable space of buildings, this fresh idea allows us to create more diverse space programs and human behavior.
