[Outline of the project] Since the Meiji era, Hibiya has evolved into a space and time for socializing and relaxation for adults, lined with the Rokumeikan, a social gathering place, and the Imperial Hotel, which was born as a Japanese guest house. Mitsui Fudosan Co., Ltd., the business owner, promotes the gathering and exchange of various cultures, sensibilities, and talents from all over the world in Hibiya, with "In the Park," "Entertainment," and "Elegance" as values unique to the city of Hibiya. We are developing a town that creates new future-oriented experiences and values. We are in charge of the commercial environmental design, production and construction of the commercial floors from the first basement floor to the third floor above ground. With the business owner's thoughts and concept design concept of "theater space city", we have created a bright and gorgeous space full of adult charm that is suitable for Hibiya, a sacred place for arts, culture and entertainment. The three-story atrium, which is modeled after a traditional theater space, spreads out an elegant space with gentle curves. In the basement arcade, the memory of the city has been inherited by reconstructing it with a modern concept design based on the motif of the Sanshin Building, which was once a symbol of Hibiya in this area. <Our project members> [Sales and project management] Yo Nishimoto, Kazuya Senda, Shinpei Watanabe [design, layout] Yukio Suzaka, Yusuke Matsumoto, Chikako Hatanaka [Production and construction] Keisuke Toda, Shinjiro Iwata, Kataka Odajima
