Buildings are anchored to the ground, but the Earth is constantly in motion. Its rotation and revolution generate "time" through difference and repetition, bringing the cyclical changes of seasons and day and night to our daily lives. Various environmental elements such as light, wind, and trees have their unique rhythms, and we continue to grow while enjoying or resisting them. If the essence of the environment lies in "change," or rather in "temporal difference," then architecture needs a "flexible scenario" that responds to difference, much like an improvisational performance. In this sense, architecture is an "experience of time" that deepens over the years through familiarity. We aim for a "differential architecture" that leads to daily discoveries, considering human growth and changing activities, rather than being confined to a building as a fixed "container."
