It is a very small residence and office with bay windows all around in Tokyo. We created a space where each person could spend time choosing his or her place by layering bay windows that function like traditional Japanese verandas all around each floor. Sitting, working as a desk, sleeping, decorating as a shelf, and various activities occur in bay windows. By the environmental analysis, it was made to be the tower which included the location of various environmental features in four seasons, time, floor and direction. The most comfortable place at any given time is taught by your two cats.
