New construction in Shenzhen has been rapidly expanding to east and west of its city center in the past few decades. As the city expands horizontally, at some critical junctures such as the China Resources Headquarters site, a tall tower becomes beneficial to draw people, sustain a good level of urban density and to function as a vertical marker. Spring bamboo shoot became a great source of inspiration as it is fast growing, self-generating and considered a very sustainable crop. Its geometry is also very powerful with its pure and absolute circular plan and graceful curving section.
Problem Statement and Project Solution
overall mass of China Resources Tower is defined by 56 exterior columns with diagrids at the bottom and converging to a point at the top. This structural solution is more fitting to the form of tower and more efficient than the mega column system. The exterior frames are fabricated offsite in three-storey module, making the construction time and cost effective. It is the first time the tube-in-tube external column structural system is realized in a supertall tower in a seismic zone in mainland China. Looking into the interior, the eccentric column beam connection helps to offer an uninterrupted column free space. The idea of providing an open space is highlighted at the 40.5-meter-tall sky hall where a lightweight space frame structure is introduced.
Creation Process & Result
The China Resources Headquarters tower anchors the burgeoning Houhai District with a design distinguished by its innovative structure and geometric precision, relaying a cultural message about the company’s history and growth.Inspired by the spring bamboo shoot, the 400-meter tower features a light, stable and fast-to-erect tube and diagrid system that is expressed in its tapered, sculptural form. Rendered in pre-fabricated column and steel units, the system affords column-free interiors, in turn allowing greater expression of the tower’s radial symmetry and more boutique floorplates as it rises.
The 56 vertical columns converge into 28 columns at the lower and upper sections of the tower, forming a series of entry portals at the tower’s base and merging to a singular point at its peak. At these junctures, faceted, triangular glass panels illuminate at night with a jewel-like brilliance across Shenzhen’s waterfront business district.In particular, the tower’s “sky hall” is as a conical, cathedral-like space offering visitors stunning views of the diagrid spire - it is one the few high-rises in the world in which people can occupy its absolute highest point. In this vein, China Resources Headquarters also crowns the larger, KPF-planned development that stitches retail, residential, and office amenities with 2,000 square meters of public space and the city’s greenbelt and waterfront. Together, the tower and complex invigorates Shenzhen’s urban fabric while providing one of the country’s premier companies with a visual icon for its historic growth and stature.
How does the project reflect the exhibition theme "Cultural Bay Area • Humanistic Design"?
One of unique features in the tower is the fact that its overall form, its structure and its façade are all in one. The design process has been similar to that of traditional Chinese stone or wood carving art. Not only they are beautiful cultural artifacts but also such technique helps to demonstrate a great sense of lightness, permeability and craftsmanship. Shaping of the overall massing came first, sculpting away everything but the structure came next and detailing the leftover structure came at the end.
graceful curving form is also a reflection of the sweeping shoreline of Shenzhen Bay. Its profile and expressive structural system also work as an ensemble with the Shenzhen Bay Sports Center, as a pair of vertical and horizontal building. The stainless steel exterior column cladding makes the tower shimmer, making the entire tower appear like a white lighthouse by an ocean edge.
