4. The Completion of the Tosabori Daibiru Building

In December 2007, construction began on the Tosabori Daibiru Building (in Tosabori, Nishi-ku, Osaka) as the company’s next big project following the Nakanoshima Daibiru Building. Nikken Sekkei designed the building and supervised the project, and a joint venture consisting of Takenaka Corporation, Obayashi Corporation, and Konoike Construction Co., Ltd. was responsible for construction. In 2002, Daibiru acquired the Tosabori Building (on a site 694.14 m2 in size with total floor area of 5,620.25 m2) in Tosabori from the Japan Research Institute, Limited and leased it in its entirety to the Japan Research Institute as Estate Naniwasuji. This construction project involved the site of Estate Naniwasuji as well as the sites of the adjacent Tosabori Warehouse, Tosabori Mansion, and parking lot, which were under Daibiru’s management.

  • The Tosabori Daibiru Building

The Tosabori Daibiru Building, which was completed in July 2009, had 17 aboveground floors, one underground floor, and three penthouse floors, with total floor area of 37,497 m². The exterior was a mosaic of white and black stone, and the entire design featured a gradient of colors becoming brighter from bottom to top. There were also wide glass corner windows at the four corners, and the building had a stately yet graceful appearance. The entrance hall, which served as the face of the building, contained an atrium nine meters in height that created a sense of openness and spaciousness.

Additionally, the office spaces on the office floors were column-free with corner windows at all four corners to provide scenic views, lighting, and a sense of openness, as a means of enhancing usability for tenants. The office zone was occupied by the Japan Research Institute and other major companies.

Furthermore, as a pro-environmental measure, Daibiru established a lush green “relaxation and recuperation garden” on the Naniwasuji side to mitigate the heat island effect and contribute to the urban environment.
