The earth constantly moves in a fixed cycle although a building never moves once it is settled on it. Such a cycle carries seasons and various changes in our daily life, that is to say “temporal difference,” which fosters our growth. When we listen to those daily rhythms, we will find it is more important to create different places to evoke various experiences, and a flexible scenario to manipulate them, rather than rooms limited for  specific functions. Architecture depends on a kind of “time experience” that can expand its own depth as we get used to it with a long duration. What we propose is not a building as a predetermined container that ignores our future progress and change of activities, but “Differential Architecture” which can lead our daily lives to the continuity of discoveries.
