[Project Overview] Since the Meiji era, Hibiya has evolved as a place that provides a space for adults to socialize and relax, with the Rokumeikan, a social gathering place, and the Imperial Hotel, which was born as Japan's state guesthouse, standing side by side. Mitsui Fudosan, the project owner, has positioned "In the Park," "Entertainment," and "Elegance" as the unique values that Hibiya offers, and is creating a city that encourages the gathering and exchange of various cultures, sensibilities, and talents from around the world, creating new, future-oriented experiences and values. Our company was in charge of the commercial environmental design, production, and construction of the commercial floors from the basement to the 3rd floor above ground, and based on the concept of "THE PREMIUM TIME HIBIYA," we aimed to create a bright and glamorous space full of adult charm, befitting Hibiya, a sacred place for arts, culture, and entertainment, with the project owner's desire to provide visitors with a special experience in a luxurious time and space, and the concept design concept of a "theatrical space city." The three-story atrium, which is inspired by traditional theater spaces, is an elegant space with soft curves. The underground arcade inherits the memory of the city by reconstructing the "Sanshin Building," which was once a symbol of Hibiya in this area, with a modern concept design. <Our Project Members> [Sales & Project Management] Yo Nishimoto, Kazuya Chida, Shinpei Watanabe [design, layout] Yukio Kazusaka, Yusuke Matsumoto, Chikako Hatanaka [Production & construction] Keisuke Toda, Shinjiro Iwata, Yoshitaka Odajima
