Appreciation towards Zhang Bing & Atelier Groundwork Architecture for providing the following description:

The Wing Stairway is designed as a transportation infrastructure that improves the circulation of commercial traffic and enriches the spatial experience within the courtyard of Jiangsu Shunyu Investment Headquarters. The entrances of the Stairway guide people coming from different directions and serve as important edges of connection to surrounding buildings, which organically give rise to the unique geometric shape of the stairway and set its place on the site.

The vivid and dynamic Wing Stairs is both an important landscape installation and a observation deck in the courtyard. The geometric folding of the Stairway gives it a sense of flexibility and unpredictability, differentiating itself from the sharp and stiff façade of the headquarters. Views will constantly change for the visitors as they walk up the stairs, which makes climbing a most interesting and exciting experience.

The Wing Stairway is a spatial truss system consisting of a series of small plan trusses interweaving with each other in space. The rigorous layout and the accurate calculation decide the section of steel elements and ensure structural stability. With its precise form and minimalism, the Stairway puts an emphasis on the structural perception, which is the most important part of the design.

The form of the Wing Stairway is unique due to the attentive design of loading transferring route. No vertical support is provided under the two resting platforms. Instead, a large suspension to resist both bending and torsion is realized, allowing the whole structure to climb up in mid-air defying gravity.

▼结构轻盈的跨越,spanning with a light structure

云梯表达了结构诗意的攀登,有双重含义: 一个是结构设计的独特追求;一个是空间攀登的诗意体验,二者通过传力路径的设计和结构构件的操控,结合空间属性得以实现。

The unique design approach of the Wing Stairway provides a poetic experience for pedestrians as they interact with its structure and geometry.
