维也纳千禧塔大堂“贝壳”改造，优雅划分功能区域

Coming out of its shell: the lobby of a somewhat outdated tower into a representative space - Millennium Tower Vienna.

贝壳里的秘密：一座昔日企业建筑大堂的华丽转变。

The Millennium Tower by architects Peichl, Podrecca and Weber soars 202 metres into the sky over Vienna. Designed as an office complex and completed in 1999, the tower is slowly beginning to show its age. This is particularly true for the lower entrance area to the tower, which shares a roof with an adjacent shopping mall to form one multifunctional centre.

由Peichl、Podrecca和Weber共同设计的千禧塔高高耸立在维也纳202米的天空中。该建筑作为综合办公楼于1999年竣工，迄今风雨十二载，已略显陈旧。尤其大堂空间作为一个衔接首层商业街区、酒店和企业办公区等不同功能区域的主要空间，已经体现不出它应有的档次。

However, as the mall context proved to be rather less desirable, the owners of the office and hotel areas of the tower wished to show a clear demarcation between lobby and shopping mall as well as a more contemporary, high-quality appearance to their clientele.

塔楼办公及酒店区域的业主考虑到客户的隐私与空间的私密性，希望以一种特殊的装置来巧妙地区分开酒店接待区与对面的购物街区，同时以这种方式来把大堂空间打造成建筑中现代、高雅、最具有一个代表性的空间。

In order to position the reception area as the new trademark of the tower, IFG ensured that it was clearly distinguishable from the mall both in terms of visual appearance and in channelling the flow of visitors toward the lifts. Our response was to attach an elaborate, shell-like carapace to the outside of the tower. A three-dimensional, fibre cement, moulded carapace is mounted onto a steel substructure, a process that required meticulous planning and production. There are two separate shells to be precise: a white, outer shell that guides visitors into the lobby and a brown, inner shell that delineates the reception area.

为了将入口和接待处打造成建筑新标志，我们不仅从视觉上，还在等待电梯的顾客分流方面，清晰地与商场分隔开来。

为此，在塔楼一侧加装了两层贝壳状立面。该立面由3D水泥纤维成型部件规律地拼接悬挂在钢架结构中，形成了别具一格的贝壳主体。白色的外层贝壳引导顾顾客往大厅方向移动；里面的棕黑色贝壳则把建筑名称刻在表面上，在引导酒店住客的同时为酒店和办公区的接待空间增加了私密性。

The 800 m² plasterboard-panelled steel skeleton is positioned as a spatial sculpture in front of the existing construction from 1999. Its organic design vocabulary and impressive form, both in its dimensions and technical execution, transform it into an identity-forming trademark. The shell serves as a protective shield for the newly created space between hall and tower: a lobby for hotel visitors and office tenants.

接待处身后是大型钢筋骨架与玻璃的拼接，一块块石膏板与其结合，像一件空间雕塑般立于1999年的建筑体前。

它们相互融合的建造语言，技术上的创新以及大胆的外壳设计给人留下深刻印象，成为标志性的象征。在大厅、塔楼、以及酒店房客和租户接待区之间新营造出一个新的空间，用贝壳的环形躯体将这个区域很好地保护起来。

The 'sky' is hung with a multitude of pendant luminaires, bisected by a long, curving, decorative lighting element that appears to encircle the tower. Altogether, the shell-like construction creates an optical suction effect that pulls visitors inside. The iconographic shell thus becomes the new calling card of the Millennium Tower. And ensures that it retains its relevance to businesses as a prime office location.

从空中悬坠的长短不一的吊灯让人不禁联想到“星空”。围绕着整座装置的外围还设计了一圈长而弯曲的光效装饰。外形结构整体上具备了一种视觉冲击力，为吸引访客带来了不少仪式感，让自身变成了千禧塔建筑的新名片。
