The design divides the format into three parts, the office zone, the main venue "IN space" and the multifunctional space. The office zone is located in the north, with independent display surfaces, connected to the venues; the high traffic main venue "In space" is located on the south lower floor for ease of movement; the other six multi-functional venues occupy the upper part of the building, connected by a high-altitude interactive atrium to provide a central platform and a congregating space for citizens.
The vertical stacking strategy enables multiple functional formats to operate independently while staying connected through public spaces, forming a perfect ecosystem of sports and industry.
To factor in traffic planning concerns, the first floor of the “In space” is extended vertically. The sunken plaza and the mechanically mobile “multifunctional hall” serve to provide more public space, entertaining the possibility of hosting large-scale concerts, "vertical marathons", and other cultural and sports activities in the future.
To maximise functional space, the elevators and evacuation passages are designed to be included within the structural framework. A truss is planted every 18 m, and robust beams are interspersed, to balance and undergird the IN space. The upper part of the truss is equipped with rods to suspend the multi-functional stadium above, forming a complete column-free space. This renders the space amenable to flexible arrangement according to the size and spatial location of the stadium. In order to strengthen lateral resistant ability, the trusses are connected by ramps and inclined beams to fashion the 3,600 m aerial circular runway featured in the project.
