About the Project

Overview With the large-scale renovation of the Hibiya International Building (completed in 1981), we aimed to differentiate the building from nearby offices undergoing new development, while also increasing added value with new ideas and revitalizing the building. By turning the sunken garden on the first basement floor into a "usable outdoor office" for office workers, we not only increased the asset value of the building, but also created a space to attract new tenants and propose work-life integration involving workers in the surrounding area of the building.
Issues/Themes Utilizing the public open space within the building site as a convenient facility for building tenants. Utilizing the plaza with a futsal court in front of the building entrance to make it easier to enter the building. Improving satisfaction for employees in the building and creating a hot topic spot.
Space Solution/Realization As a place for new ways of working, we planned a "permanent outdoor office" rather than a temporary one. It is different from conventional pocket parks that are based on park functions, and incorporates many functions of an ABW office (※). By allowing people to choose where they want to work based on their mood and purpose, this facility will propose and lead new ways of working in Hibiya.
The scaled-out grid layout controls the rustic feel, while incorporating the sophistication that is unique to the city. The clever placement of tall trees makes use of the atrium to create a perfect blend of relaxation and urban atmosphere, enhancing comfort.
*ABW (Activity Based Working): A work style in which you choose where to work based on the nature of the work.
Design for Environment Universal design: Taking into consideration the diverse range of workers and small children visiting from the adjacent Hibiya Park, the walkways are wide, the grass is laid to reduce pain if a person falls, and seating areas are low and deep.
Safety design: Because it is a facility that anyone can use, consideration was given to rounded corners, anti-slip properties, and good drainage, and large fixtures and trees over 5m tall were constructed to withstand wind speeds of over 50m/s after structural calculations. In addition, everything is covered with grass to act as a cushion in case of falls.
