在深圳前海深铁置业的建筑设计竞赛中，BIG的“PRISMA”方案获胜，方案包括一座300米高的住宅楼和一座250米高的办公楼。这个项目将成为前海湾新开发计划的一部分，进一步巩固前海作为深圳新兴金融和文化中心的地位。

BIG设计的前海Prisma大厦坐落于深圳前海的桂湾区，位于桂湾入口处被称为“绿廊”的深港广场两侧。项目包含新的办公空间、住宅和逾2万平方米的多层公共空间，距综合区域交通枢纽和前海湾仅几步之遥。

BIG’s ‘leaning’ Qianhai Prisma Towers, featuring a 300m tall residential tower and a 250m tall office tower, will complete the new Qianhai Bay development, solidifying Qianhai’s position as the burgeoning financial and cultural center of Shenzhen. Expected to begin construction in 2025, the project – won in a global architectural competition – will be BIG’s second in Shenzhen following Shenzhen Energy Mansion’s completion in 2017.

Situated in the Guiwan District within the metropolitan city of Qianhai, the BIG-designed Qianhai Prisma Towers will flank each side of the Shenzhen Hong Kong Plaza – also known as the ‘green belt’ – marking the entrance to the neighborhood. New workspaces, residences, and 20,000+ m2 of multi-level public spaces will be positioned steps from an integrated regional transport hub and the Qianhai Bay.

▼项目概览，Overall view

两座塔楼自地面向天空延伸，形态随着优雅的倾斜角度逐渐收缩，不仅提升了结构效率，也在塔楼和宽敞的底层公共区域之间创造了绿意盎然的开口。阳台上郁郁葱葱的自然景观与玻璃幕墙形成鲜明对比，而玻璃的外墙随着一天不同时间的天光变化，映射出丰富且微妙的光芒。

Both towers are defined by gently leaning volumes that taper towards the sky – a subtle gesture that adds structural efficiency while creating verdant openings between the volumes and a generous ground-floor public realm. The lush biophilia on the balconies and ledges contrasts the glass facades that shimmer subtly throughout the passing of the day.

塔楼的地面层充分打开，打造了一个充满活力和温馨氛围的城市客厅，同时将塔楼连接到“绿廊”和附近的购物中心。蜿蜒的亲自然人行天桥发挥了天篷的作用，在连接购物中心、零售裙楼和周围社区的同时供人们遮荫和避雨。

The ground plane of the towers opens up to create a dynamic and welcoming urban living room while connecting the towers to the ‘green belt’ and nearby shopping mall. A meandering biophilic pedestrian skybridge functions as a canopy, providing shade and protection from the rain while connecting the shopping mall, the retail podium, and the surrounding neighborhood.

透过建筑外墙上的开窗向内部空间看去，层层叠叠的绿色露台从地面层一直延伸到屋顶，来往的上班族和游客可以在这里欣赏到前海湾360度的全景风光。倾斜的办公大楼在西立面和东立面的连梁上设置了光伏电池，以最大限度地提高建筑的光伏效率。为了更好地应对当地气候，实现并改善热性能，办公楼结构最为暴露的部分设置了双层封闭空腔幕墙系统 (CCF)。 住宅塔楼内每个单元的窗框都设置了可开闭的通风口，实现自然通风。

Peeking through the building envelope openings, cascading green terraces are introduced from the street level and up to the roof, where office workers and visitors can enjoy 360-degree views of Qianhai Bay. PV cells are integrated in the slightly tilted office tower’s West and East façade spandrel to maximize the PV efficiency. To better respond to the local climate achieving and improving thermal performance, double-skin closedcavity façade (CCF) is used for the most exposed orientation of office tower. The apartment tower units have operable ventilation inlets built into the window frames to allow for natural ventilation.
