2023 Asian Games Masterplan and Hybrid Buildings

CHALLENGE
Selected from a group of 5 international firms, Archi-Tectonics won this invited competition for the 2022 Asian Games in Hangzhou/ China. The project faced three major challenges. First, it had to transform the 1.6 kilometer site bisected by a major road and river into an active public eco landscape. Second, the design had to offer facilities tailor-made for the Games events that would remain useful after they ended, as well as an expansive fitness center and exhibition / visitors center. Third, it had to set the course for sustainable, ecologically conscious development in Hangzhou, one of China’s densest and fastest-growing cities.

INNOVATION
Archi-Tectonics incorporated 7 buildings into an ECO landscape where the requirement was to have 85% park. The 2 stadiums on opposite ends of the site serve as anchors & generators of new activities, and are connected by a pedestrian shopping valley that passes under the road and river. Named the Valley Village Mall, this pedestrian spine is lined with shops, restaurants, cafes, kiosks, and outdoor gathering areas. To transition the park after the games, the design creates two hybrid stadiums, and activities such as shopping, hiking, birdwatching, boating, outdoor concerts, and major cultural events.

IMPACT
Using a zero-earth landscape strategy, the excavated earth from the restored wetlands and valley is re-used to create a rolling hillscape with porous pavement. These interventions turn the site into a “Sponge City” that collects, filters, and reuses rainwater for water features, irrigation, plumbing, heating and cooling. The park extends the activity of the city streets into the landscape to integrate the much-needed green heart to the area, strengthens and diversifies the ecology its entire context, and creates a new center of public life in Hangzhou that will be used long after the Games end. The design is well-equipped to house activities like nature walks, basketball and skateboarding, shopping, picnics, waterfront dining, community events, and more.
