Tianjin China Overseas International Center

After winning an international competition, HOK is designing the Tianjin China Overseas International Center. It includes two office towers (the tallest is 71 stories) and a retail podium that acts as an entry to the development.

The site is in the heart of Tianjin’s central business district (CBD), on the east bank of the Haihe River.

The world-class office space, integrated sustainable strategies including a high-performance building envelope, ample green spaces, desirable amenities and luxury retail brands will position the development as Tianjin’s premier commercial venue.

HOK’s design emulates the modularity and structural grid of the neighboring buildings while achieving a contemporary, sculptural effect. As a new landmark for Tianjin, the 71-story tower appears to twist from the bottom to the top. HOK’s architects collaborated with structural engineers at Thornton Tomasetti and the Tianjin University Research Institute of Architectural Design and Urban Planning Co. to seamlessly integrate the twisting tower facade with the building structure. The glass curtain wall, which contrasts with the elegant, modular skin system, provides unobstructed city views while drawing daylight deep into the building.

Located on the 41^st and 42^nd floors of the main tower, the “Sky Lobby” features an outdoor sky garden, fitness and recreation area, dining areas and a lounge. The garden terrace complements the complexity of the tower’s form and brings nature into the workspace.

A four-story observation deck atop the 71-story tower offers panoramic city views while accommodating a sky bar, fine dining and a multifunctional exhibition hall.
