Solidifying Qianjiang Century City as a vibrant, cultural center along the Qiantang River, Hangzhou IOC provides a mixed-use destination for the public across two towers.
Hangzhou IOC is designed to serve as a central point within the greater IOC development, as well as a landmark to the city. The shorter of the two towers, rising 200 meters, is dedicated to office space, while the taller is comprised of serviced apartments, office space, and hotel programming that occupies the upper third of the tower. Through a range of floorplate sizes due to each towers’ stepped massing, the development provides flexibility that serves a broad range of tenants. The façade of each tower emphasizes the internal components through a harmonious vertical pattern that slightly varies based on programming.
The concept for the Hangzhou IOC tower takes inspiration from mountains with multiple peaks; each grounded in the earth, stretching towards the sky. The vertical quadrants are bundled together to create a single unit, embodying strength and stability. This stepped and elongated massing form sculptural silhouettes that house landscaped terraces. Both within the towers and from an observation deck within the 300-meter tower, visitors are offered unique vantage points, as the towers leverage the water’s winding configuration for optimal riverfront views.
The IOC podium connects the two structures and houses multiple lobbies in addition to a retail and event space. At the center of the podium is a circular garden, open to the sky, that continues downward as it allows light to reach into the basement car park entry so that greenery can flourish below ground level.
