This is a head office renovation project for Nice Co., Ltd., a distributor of wood and building materials, celebrating its 70th anniversary. We were selected as the result of a proposal competition. Based on the concept of "knowing trees and communicating about trees," we aimed to build a base where wood specialists can gather and create a sustainable circulation centered on wood, thereby aiming to be a "facility that contributes to creating a bright society with trees" that can further stimulate the distribution of wood. The first and second floors, where visitors are welcomed, and the eighth floor, which has a reception room, were considered to be places that could appeal to customers, and were concept design using Nice's original wood products as materials. In the lobby, the dynamic wooden colonnade that stretches up to the high ceiling of the atrium and the vertical blinds made of lace material attached to the large glass windows gently block the view from the outside world, and the scattered glass lamps express the sunlight filtering through the trees, making the most of the large space to create a hospitality space. On the 7th floor, where employees gather, we have set up a conference room and a reading corner so that employees can enjoy and spontaneously interact with "trees." It is a place for artisans to gather and browse technology. By creating spaces where employees can concentrate and spaces that encourage active communication, we have created a flexible space configuration that caters to the working style of each employee. [Social issues/customer issues/requests] The specific request for this renewal was to share concept design and values that symbolize sustainability, such as "carbon-free and wood-based," and to create an office environment that improves communication during the COVID-19 pandemic. [Solution] In order to realize the strong desire for wood-based materials, we communicated closely with NICE's project managers and their own factory managers, and proceeded with concept design while deciding on the materials and color of the wood. The communication area for employees is intentionally designed to have no boundaries, and the area is softly divided by furniture such as a family restaurant bench and a solo desk where you can concentrate on your work, centered around an arched bookshelf. By making it an OA floor, it has the function of realizing a flexible working style. [Customer feedback] NOMURA took on the project, and thanks to them we were able to create a welcoming space that is reminiscent of a high-quality, relaxed hotel lobby, something we would never have dreamed up ourselves. This time, they used a variety of their own products and tree species as materials. What could have easily been a disjointed impression was managed to exquisitely harmonize the characteristics of the tree species with the space, achieving a wooden renovation befitting a company with roots in "wood". We are extremely grateful that this was made possible by NOMURA 's high level of concept design and technical capabilities. <Our project members> [Development] Kitai Takuya [Sales and project promotion] Kitai Takuya, Nakayabu Midori, Yoshii Seijun [design, layout] Taibichi Sachiko, Hiura Nao [Production and construction] Hirowatari Ryokazu, Iwashita Nozomi, Kikuchi Nohara
