[Project Summary] Since the Meiji Period, Hibiya has evolved into a place for adults to socialize and relax, with the establishment of the Rokumeikan, a social gathering place, and the Imperial Hotel, which was born as a Japanese guesthouse. The project owner, Mitsui Fudosan, has created a town that creates new future-oriented experiences and values by encouraging various cultures, sensibilities, and talents from around the world to gather and exchange in Hibiya, with the unique values of the city being "In the Park," "Entertainment," and "Elegance." Our company is in charge of the commercial environmental design and construction of the commercial floors from the first basement floor to the third floor above ground, and based on the concept of "THE PREMIUM TIME HIBIYA," we wanted visitors to have a special experience in a luxurious time and space, and with concept design concept of a "theater space city," we created a bright and glamorous space full of adult charm, suitable for Hibiya, a mecca for arts, culture, and entertainment. The three-story atrium, inspired by traditional theater spaces, has an elegant space with soft curves. The underground arcade will be reconstructed with a modern concept design based on the motif of the Sanshin Building, which was once a symbol of Hibiya in this area, to preserve the memory of the town. <Our project members> [Sales/Project Management] Yo Nishimoto, Kazuya Senda, Shinpei Watanabe [design, layout] Yukio Suzaka, Yusuke Matsumoto, Chikako Hatanaka [Production/ construction] Keisuke Toda, Shinjiro Iwata, Keita Odajima
