The earth constantly moves in a fixed cycle, although a building never moves once it is settled on it. This cycle brings seasons and various changes to our daily lives, which we call "temporal difference," and it helps us grow. If we pay attention to these daily rhythms, we will find that it is more important to create different places that evoke various experiences and a flexible scenario to manipulate them, rather than rooms that are limited to specific functions. Architecture depends on a kind of "time experience" that can expand its depth as we get used to it over a long period of time. What we propose is not a building as a predetermined container that ignores our future progress and changes in activities, but "Differential Architecture" that can lead our daily lives to a continuity of discoveries.
