SOM recently just unveiled the first images of a spiraling mixed-use tower planned for China. The Hangzhou Wangchao Center features an undulating glass façade and eight mega-columns that slope outward at the corners. This design helps to minimize wind loads and optimize the center’s performance and efficiency.
The Center will offer hotel, office and retail spaces in the heart of Hangzhou. As a result of an integrated architectural and engineering strategy, the tower’s distinct silhouette minimizes wind loads and creates flexible floor plates.

In addition to the large sloping corner columns, architects designed secondary perimeter columns that branch out to maintain equal column bays. A Vierendeel transfer truss above the lobby connects the secondary columns to the corner columns. This structure allows for the use of planar glass panels as cladding material.
The tower is slated for completion in 2021. SOM said, “Located at the intersection of several major transportation networks, the tower is a beacon of performance-driven design and is emblematic of Hangzhou’s future as a new global destination.”
