This is a renovation project for the Toyobo Building, located along the Dojima River in Osaka, an area brimming with charm thanks to its numerous historical buildings and abundant nature. The Dojima River is a representative river of Osaka, known as the "City of Water," and the aim was to create a space where people can work vibrantly while enjoying the pleasant atmosphere of this location. The plaza features an exterior design that makes it seem as if a riverside deck extends to the building, and a swaying willow tree is placed as a symbolic tree, allowing people to visually feel the river breeze. The facade incorporates concept design inspired by the grandeur of the Dojima River and the density of its waves. The building's exterior walls are wrapped in a soft wave design to harmonize with the building while also aiming to become a new symbol of the city. The lobby lounge's design harmonizes with the facade, creating continuity between the interior and exterior, and comfort is created by employing various types of sofas and original acoustics. In addition, visual art that visualizes the outside environment, such as temperature and wind, is applied to the central pillar, creating an atmosphere where the pleasantness of the river breeze can be felt indoors. Each floor features photographs of the Dojima River, showcasing its diverse expressions, while the restrooms are adorned with original artwork that delicately depicts waves, creating a different color palette on each floor that will surprise visitors.
