Located in a dense residential district in Tokyo, this property is distinguished by its triangular shape formed by two roads meeting at a sharp angle. The voids function as spaces that are continuous with the surrounding environment, residents, and neighborhood—in other words, with the exterior.They serve to "modulate connections" with the exterior. The three voids modulate relationships between these elements of the interior and exterior. This modulation enables just the right degree of interaction, and ultimately, leads to harmonious coexistence with the surrounding environment.
