“中國尊”大廈位于北京新建30公頃中央商務區(qū)核心區(qū)。在2018年竣工后，其將成為該地區(qū)一顆璀璨的明珠及華北地區(qū)第二高大樓。

在北京最高的塔樓底部，一個沙漏狀的幕墻以精致的雙曲線形式懸掛在入口處，標志著其在地面層的平緩著陸。 此設計靈感源自中國傳統(tǒng)禮器-“尊”的外形。

設計團隊對設計量身定做，將古代禮器外形進行抽象化處理和優(yōu)化，平衡形體設計與中信大廈的結構上的要求。超高層塔樓平面為圓角方形，而且上下寬度漸變。頂部寬度為69米，腰部寬度為54米，塔底寬度為78米。設計團隊巧妙處理了厚重的建筑與輕質(zhì)外殼之間的幾個關鍵姿態(tài)，使這個高聳的結構優(yōu)雅地立于地上。譬如，肋板寬度在大廈頂部及底部以一定比例加寬，同樣的效果也運用在定制的室內(nèi)天棚上。

大堂獨特向上曲線在相反方向上與大廈朝外懸垂的形式對稱， 并構成步行體驗的戲劇性背景。設計團隊進行了20多次設計迭代以實現(xiàn)這種天棚的效果。這需要制造能夠滿足與材料特性相反的彎曲的獨特鋁板。這些鋁板跨過正交玻璃張力幕墻與立面交接，形成主入口的懸挑結構。這個結合點再次展現(xiàn)中信大廈設計的一個主要原則：即使在超高層建筑尺度上，該大廈依然保持與毗鄰城市環(huán)境的親密關系，并展現(xiàn)內(nèi)部辦公空間的創(chuàng)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.
