This is the new headquarters of a Ginza-founded logistics company marking its 100th anniversary. Two buildings on separate city-center plots, divided by a district road, are integrated into one headquarters complex. Community-oriented functions, including a parcel delivery center and a café, are included. The spatial composition fosters a sense of unity between the buildings and the city. Wooden stepped platforms create a flexible workplace for future work styles. As a company responsible for distribution functions, it embodies its relationship with society and its commitment to the environment through a wood-based office open to the city.
The airspace above the road dividing the two sites is conceived as an atrium, incorporating it as an element that connects the workplace. By varying floor and ceiling levels facing the road, diagonal sightlines and broad mutual views are created, fostering a sense of unity among workers. The stepped wooden floor generates ceiling height variation from 2.1 m to 4.4 m within standard office floor heights, creating workplace options distinct from universal space. The evacuation stair lands on the level-shifting floor, transforming the sense of distance when moving between floors.
A free address layout combines level differences with custom furniture, enabling workers to select settings suited to different tasks. A timber canopy flows from street to interior ceiling, forming a distinctive second façade that softens the streetscape. Set-back columns preserve unobstructed city views.
At ground level, a parcel delivery center and café occupy a publicly accessible threshold, serving employees and community.
Environmental controls allow smartphone adjustment of lighting and airflow. Compared with conventional offices, air conditioning energy is reduced approximately 20 percent and lighting energy roughly 50 percent. Wood cladding cuts manufacturing CO2 emissions by about 90 percent versus metal, with wood sequestering CO2 equivalent to a cedar forest 2.3 times the site area.
The design coordinates spatial continuity, user choice, and environmental intent into coherent architecture connecting workplace and city.
