CHALLENGE
This 6500-seat centerpiece for the Hangzhou Asian Games 2023 Park is located at the south end of the park entrance and accessed via two curved bridges. The 35,000 m2 structure is designed to function as an attractor and generator of new socio-cultural activities and hence was proposed as Hybrid; merging sports events with a concert hall / event space for Hangzhou after the games. Archi-Tectonics took the initiative already in the competition phase to engage Thornton Tomasetti, to come up with the most innovative structural solutions. A long-span Suspendome or Superdome roof makes it possible for the lobby spaces to be entirely column-free, reinforcing the adaptability and hybrid nature of the building. The roof sits on the inner bowl and cantilevers out over the lobby to support the outer shell, a spectacular steel and glass diagrid skin.

INNOVATION
Hybrid - Starting with a geometry inspired by the Cong, an ancient Hangzhou jade-stone artifact that takes the shape of a square tube with a circular bore, Archi-Tectonics used a parametric design process that optimized this shape to allow the stadium to efficiently convert from a sports arena to a performance venue after the Games. The process generated multiple iterations based on input criteria that optimized the stadium for both arena and concert hall seating.
Efficiency - Using the 3D digital design process, Archi-Tectonics was also able to achieve the complex steel & glass diagrid facade with as few unique modules as possible, making for efficient coordination with international fabricators and construction teams. The 8000 brass shingle were modulated in just 85 variations, optimizing this building's double curved intersected volumes.
Column-free - A long-span Suspendome or Superdome roof makes it possible for the lobby spaces to be entirely column-free, reinforcing the adaptability and hybrid nature of the building. The roof was computationally optimized to be constructed and installed on site in just 15 segments. The roof also facilitates the entire space to be naturally lit and ventilated. A large oculus brings natural light into the bowl, using a large sculptural deflector to soften the sunlight and diffuse it evenly throughout space. A continuous band of operable windows below the stadium roof facilitates natural ventilation of the entrance lobby and main circulation space surrounding the inner bowl. These windows also allow natural daylighting to enter below the cantilevered Suspendome, enhancing the sensation of a floating roof.

IMPACT
The building achieved 'Green Building Evaluation Label 3 Star' (GBEL 3 Star), the highest level of sustainability in China and equivalent to LEED Platinum. The hybrid stadium & concert hall—in tandem with supporting spaces like restaurants, VIP lounges, and retail areas throughout the building—creates a layered and dynamic environment: more than just a container for viewing sports or performances, the building serves as a fully-equipped events and entertainment destination.
