This project involved the renovation of the commercial area of the Matsushita IMP Building, an office building located in Osaka Business Park. Since a previously planned train station still remains underground, concept design motif was chosen with the hope that the building would become a hub where people gather, just as it was originally intended. Throughout the building, the circular columns extending across multiple floors feature a powerful mortar-like finish and metal framing, creating a base for a colonnaded space reminiscent of a train station. In the western atrium, this framing forms a continuous arch shape, like the arcade of a train station, creating a sense of unity with the existing curved ceiling. Within this, the black/gold/verdigris colors, stone walls, and plum blossom shapes of the adjacent Osaka Castle were incorporated into the FF&E (front and rear window) and structural elements, creating an affinity with the memories this land has inherited for 400 years. Furthermore, amidst the COVID-19 pandemic, as many companies have developed environments that allow employees to work outside the office, the project explored how a commercial office building can adapt to new work styles by creating workspaces in the common areas of the commercial space. Throughout the commercial area, we have placed furniture that can accommodate a wide range of needs, from meetings to individual work. Each piece of furniture incorporates various features, such as sofas with L-shaped expandable tabletops, high-back chairs that restrict the view to enhance concentration, and counter chairs with coat hangers. We have also considered comfort by placing plants like partitions, making it a space that can be used primarily as a workspace on weekdays and as a resting place for tourists on weekends. We aimed to create an open workspace where a diverse range of people can gather, including office workers in the IMP Building, people working in Osaka Business Park, and even visitors, fostering new ways of working and new forms of communication.
