云梯位于江苏舜禹投资总部塔楼与裙房的交接处，主要功能是改善商业动线及丰富建筑组团的院落空间体验。作为典型的交通设施，楼梯的各入口合理地顺应了不同方向的商业人流，交通便捷性的设计考虑自然形成了折线状的平面几何关系，由外而内地确立了楼梯在场地中的秩序。

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.

设计将云梯作为院落空间内最重要的造景和观景装置。云梯的外部形体因折返的轮廓而具有随性和松弛特质，恰恰与背景的总部建筑的匀质挺括线条风格迥异，使云梯成为最为活跃的造景元素。当沿着云梯逐渐攀爬，景观会连续变化，空间体验得以强化。

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.

云梯由一系列相互交织的桁架结构组成，各构件彼此支撑，共同组成了空间桁架结构，因此具有了良好的结构稳定性。依据细致的设计和精确的计算，不同钢杆件截面的均依据内力大小控制，从而使得云梯的结构具有了精确形式和极少主义特征，结构精致诱发的结构感知成为空间体验的重要组成部分。

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.

云梯的独特结构传力路径使其具有了独一无二的结构形态。云梯的二级中间休息平台底部均不设任何竖向支撑，使结构轻盈的跨越和大尺度悬挑，结构在在视觉上仿佛摆脱了重力束缚，漂浮于空中，举重若轻。

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.

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.
