美中不足的用地
项目用地位于深圳市福田CBD,临近市民中心。本来这个区位非常好,可惜的是周边已高楼林立,沿城市主干道几乎没有展示面;同时,这块地面积虽不大,却分属两家银行业主。
城市设计建议通过两家整体设计开发,并在用地中央合建一个零退线的「共享大厅」作为入口,来缓和用地紧张的局面。然而两个业主并不希望建一个真正的「共享大厅」,以免产生共有物业的权属问题。这成为本次设计的两大难点。
Text description provided by the architects. The project is located near the Civic Center in Futian district, CBD of Shenzhen. Theoretically, this is a good location, but unfortunately, there are already many tall buildings in the surroundings so that the project can hardly be seen on the arterial roads. Besides, although this block is small, it’s owned by two banks. From the perspective of urban design, it suggests that through the overall design and development of the two parties, a “shared hall” should be built as an entrance at the center of the plot. But the two owners were not willing to build a real “shared hall”, for fear of ownership problems of shared properties. These are the two major difficulties of this design.

以退为进的策略
我们选择了以退为进的策略来破解项目中的矛盾。
We chose the strategy of “retreating in order to advance” to solve the contradictions in the project.

一方面,我们决定不去讨论到底设计出怎样标新立异的塔楼能在周围楼宇的夹缝中与他们争奇斗艳,而是设计两座方整简约的塔楼,以理性谦逊的姿态融入到整个中心区的城市肌理中,这实际上也符合银行建筑庄重低调的气质。
First, instead of discussing how to design an unconventional tower building that can compete with others in the surroundings, we chose to design two upright and simplistic tower buildings; Second, we shifted the design focus from the tower building to the base of the building, trying to create a distinctive urban public space, a landmark of urban life in the densely built city center.

另一方面,我们把设计的重心由塔楼转移到近人尺度的建筑底部,试图在中心区密集的建筑森林中,营造一个具有特色的城市公共空间,打造一个城市生活的地标。在这里我们打了个「擦边球」,偷换了原有「共享大厅」的概念。
我们用一个流线造型的裙楼将两座塔楼在形式上紧密粘合在一起,但其底部却是一个完全开放给城市的公共通道。通道在场地正中央放大,形成一个高大的玻璃穹顶。办公的人流先进入到这个穹顶之下,再分别进入两家银行的办公大堂。
Here we played an “edge ball” and changed the “shared hall” concept into a streamlined podium building that connects the two-tower buildings together, yet with a public passage that is completely open to the city at the bottom. The passage is enlarged at the center of the site, forming a tall glass dome.

穹顶顶部设有天窗,当阳光射入的时候,经由玻璃的反射和折射产生普通直面玻璃建筑所不具备的水晶般的光影效果,营造出一种前所未有的入口前厅的体验。
这个入口前厅由于完全开放,又具有很强的城市属性,为往返附近物业及公共交通站点的人提供了一个有趣的,能遮阳避雨的捷径通道。它从预设中私有的「共享大厅」转变成了真正「与城市共享的大厅」。而两家银行也回避了他们担忧的物业权属不清会造成的管理问题。
由此,两家业主以及城市,这三方的利益都得到了照顾,整个项目也由于这个共享大厅强烈的雕塑感造型和特殊的光影效果而获得了新的标志性。
There is a skylight on the top of the dome. When sunlight shines in, the reflection and refraction of the glass produce a crystal-like light and shadow effect that is not available in ordinary straight-faced glass buildings. This entrance hall is completely open and provides a playful shortcut to shading and sheltering for people from nearby properties and public transportation stations. It has transformed from a “shared hall” to a real “hall shared with the city”. The two banks also avoided the management problems.

尽管塔楼形体方整简单,我们还是对立面植入了细微的处理。我们以竖向遮阳百叶为主元素,但百叶在塔楼顶部以及受太阳辐射最多的角部扭转为45度,长度比垂直的部分更长,遮阳效果也更佳。
一眼看过去,这个塔楼并不出众;但由于这个扭转的存在,在某些光线角度看似乎又蕴含着戏剧化的、耐人寻味的效果,试图探索一种「和而不同」的美学。
For the twoer facades, vertical shading louvers are adopted as the main element, but the louvers are twisted at 45 degrees on the top of the tower building and at the corners that receive the most solar radiation. The length is longer than the vertical part and its shading effect is better. Due to the twist, the simple shading lines seem to have a dramatic effect

一些「小心思」
裙楼的流线造型从「共享大厅」延伸到西南和东北两个角落,布置公共性更强的银行营业厅、配套商业等公共功能,进一步激活空间的公共性;而西北、东南角则让塔楼直接落地。「软」的裙楼公共界面和「硬」的塔楼形象面碰撞融合,让整个建筑更加生动。
Although the podium building has a large number of curved surfaces, we still designed a standard node system to adapt to any shape and any angle of glass installation. The design which resembles the “gear” mechanism that absorbs the structural characteristics of the “unit-typed curtain wall” together greatly improves the construction efficiency.

另外,尽管裙楼有大量的曲面,几乎找不出几块相同的玻璃,我们仍设计了一个标准的节点系统来适应任何形状及任意角度的玻璃安装。通过尽可能平面化的主次龙骨结构体系,和吸纳了「单元式幕墙」构造特点的,类似「齿轮」机制的抓节点设计,大大提高了建造效率。

结语
这座建筑被一个广告拍摄到了,情景是一位女性从共享大厅的通道向画面走来,微微虚化的穹顶玻璃在正午明媚的阳光下显得波光粼粼。我们无意参与网红建筑的竞争,但希望这座建筑对城市是友好的。人们对于这些超高层建筑并非只能仰望,并且敬而远之的绕行;而是也能走进它,感受它给予城市的新鲜与包容。
