This integrated development spans two sites flanking a road near Subway Station of Kamiya-cho. Leveraging the Building Standard Law's the single housing complex certification system, the project creates a cohesive complex that continues the urban fabric of neighboring Shiro-yama Hills. A residential tower fronts wide Sakurada Avenue, while an office building occupies the opposite site. The eastern area serves as a gateway plaza to Shiro-yama Hills, while the western side features a tree-lined promenade framed by the woodlands of Sengoku-yama, integrating green pedestrian routes into the urban scale. Both office and residential buildings use earth-tone precast concrete panels—a shared design element with Shiro-yama Hills—and glass curtain walls at office building corners, fostering a unified metropolitan landscape.
