Shenzhen, Guangdong, China
Led by Lang Wang, Yiyou Zhu, and Zhen Zhang from CCDI Group-21 Design, the new Shenzhen Houhai Hongtu Innovation Plaza features a façade that uses modular units to form a diamond-shaped curtain wall, while the external structural frame adopts the steel structure rhombus oblique grid, which integrates the facade form, structural system, and internal space.
Located in the core area of Houhai, Shenzhen, the new 262m tower stands next to the China Resources Headquarters and boasts a singular presence on the city’s skyline.
The design uses a unique folded skin form to embody the coastal architecture (wave) and financial tower (diamond), giving the public an image of stability, lightness, and elegance; the podium connects the surrounding, and the swirling open volume integrates the subway,
Elements such as commerce, pedestrian system, waterfront activities, and roof gardens are combined to become a “Central Park.”
The façade of this project uses modular units to form a diamond-shaped curtain wall, the external structural frame adopts the steel structure rhombus oblique grid, which integrates the facade form, structural system and internal space; however, the stress situation and construction method of the nodes of the oblique grid are very complicated.
Therefore, it is the key point of the whole project to deeply study the node force performance of the oblique grid, to realize the safety, economic, and reasonableness of the oblique outer frame structure, and to achieve the perfect facade effect.
By studying the shape, the architects found a façade control line and based on this line, the architects found a triangular basic unit, which can be combined into the shape of a diamond, and form a folded skin through three-dimensional processing; at the same time, the facade rod is redesigned to hide the opening fan and block part of the glass, so that the exposed glass is the sharp corner of the facade, while the actual glass is a flat angle, which solves the problem that the glass angle at the sharp corner of the façade is too small and difficult to produce.
