“中国尊”大厦位于北京新建30公顷中央商务区核心区。在2018年竣工后，其将成为该地区一颗璀璨的明珠及华北地区第二高大楼。

在北京最高的塔楼底部，一个沙漏状的幕墙以精致的双曲线形式悬挂在入口处，标志着其在地面层的平缓着陆。 此设计灵感源自中国传统礼器-“尊”的外形。

设计团队对设计量身定做，将古代礼器外形进行抽象化处理和优化，平衡形体设计与中信大厦的结构上的要求。超高层塔楼平面为圆角方形，而且上下宽度渐变。顶部宽度为69米，腰部宽度为54米，塔底宽度为78米。设计团队巧妙处理了厚重的建筑与轻质外壳之间的几个关键姿态，使这个高耸的结构优雅地立于地上。譬如，肋板宽度在大厦顶部及底部以一定比例加宽，同样的效果也运用在定制的室内天棚上。

大堂独特向上曲线在相反方向上与大厦朝外悬垂的形式对称， 并构成步行体验的戏剧性背景。设计团队进行了20多次设计迭代以实现这种天棚的效果。这需要制造能够满足与材料特性相反的弯曲的独特铝板。这些铝板跨过正交玻璃张力幕墙与立面交接，形成主入口的悬挑结构。这个结合点再次展现中信大厦设计的一个主要原则：即使在超高层建筑尺度上，该大厦依然保持与毗邻城市环境的亲密关系，并展现内部办公空间的创新特色。

Located at the core of Beijing’s new 30-hectare central business district, China Zun Tower will be the area’s crown jewel, and the second tallest building in Northern China once completed in 2018.

At the base of Beijing’s tallest tower, an hourglass facade drapes over the entry in a refined double curve,signalling a gentle landing at the ground level. The design draws inspiration from the form of the “zun”, a ritualistic Chinese artifact.

Adopting a tailor-made approach, the design team abstracts and refines the historical shape, balancing its articulation with CITIC Tower’s structural requirements.In plan, the supertall tower is square with rounded corners, its width transforming vertically from its 69-meter-wide top to its 54-meter-wide base to its 78-meter-wide base. These sweeping proportions meet the ground level with particular finesse, made possible by the team’s refinement of several key gestures between the weight of the building and its light shell. For example, the width of the ribs widen proportionally at the top and bottom of the tower—an effect that translates to the bespoke, interior canopy.

The lobby’s distinct, upward curve mirrors the tower’s outward drape in the opposite direction, acting as a dramatic backdrop to its pedestrian experience. The design team tested more than twenty iterations to achieve this canopy effect, which required the fabrication of unique aluminium panels that warp antithetically to their material nature. These panels surpass the orthogonal glass tension wall and meet the facade,becoming a shallow overhang to the main entrance. This meeting point reiterates a critical tenet of CITIC Tower’s design: that even at its supertall scale, the tower’s relationship to its immediate, urban environment remain intimate while communicating its workplace innovation.
