建于1911年的阿姆斯特丹前钻石交易所“Capital C ”大楼由ZJA联合Heyligers Architects设计翻新。 这座纪念性建筑在很大程度上恢复了由Gerrit van Arkel 设计的原貌，并恢复了最初的魅力。这座宏伟建筑的顶部是一个由玻璃和钢打造的醒目圆顶“High Light”，约二十个艺术和设计项目构成了贯穿建筑的主线。

The former Diamond Exchange, Capital C Amsterdam, dating from 1911, has undergone a major renovation designed by the architectural studio ZJA in collaboration with Heyligers architects. The monumental building has been largely restored to the original Gerrit van Arkel design and has regained its original allure. The Dutch monument is crowned with a striking, spatial dome of glass and steel; the High Light. Common thread running through the building are about twenty art and design projects.

恢复与重构

Restoration and reconstruction

21世纪初，钻石交易所的建筑状况不甚理想，一场火灾、几次加建和多次改造使其丧失了最初的魅力，业已变成一座内向的巨型办公楼。 因此项目需要进行一次彻底的恢复和重建。在屋顶上，两座引人注目的塔楼、原始屋顶边缘和Van Arkel最初设计的鼓室都已恢复。入口处的瓷砖镶板是根据老照片和图纸重新制作的。为了使其成为一座现代办公楼，所有原始楼层都被完全剥离，并配备了新设施，并在功能上进行了重组。 新的空间容纳了办公室、活动空间、会议室和灵活工作场所。最大的变化是在屋顶上增加了醒目的高光：一个玻璃和钢制的圆顶。圆顶如钻石般的切割面造型让人想起这座充满纪念性建筑物曾经作为钻石贸易中心的历史。

At the beginning of the 21st century the Diamond exchange was in a poor state. Due to a fire, several additions and various renovations, much of the original charisma was gone. It had become an inward-looking office colossus. This required a major round of restoration and reconstruction. On the roof two striking towers, the original roof edge and the tympana from the original design by Van Arkel have been reinstated. The authentic tile panelings of the entrance were recreated based on old photos and drawings. To make it viable as a contemporary office building, all floors have been completely stripped, provided with new installations and have been functionally reorganized. This is where the offices, event spaces, meeting rooms and flexible workplaces are located now. The biggest change is the addition of the High Light, a glass and steel dome on the roof. The faceted diamond like form of the dome is reminiscent of the monument’s history. As centre of the diamond trade.

在屋顶加冕

Crowning on the roof

建筑的圆顶基于Gridshell（一种从双曲率获得强度的结构）的原理而建造，提供了极高的设计自由度，并为大跨度空间创造了可能。建筑采用参数化设计原则来创建轻盈透明的圆顶，每个组件是独特的。 “高光”是一种充满自信的表达，它定义了项目的面貌，同时与这座纪念性建筑保持着互相尊重的关系。玻璃穹顶的特殊空间体验，作为最新设计方法和技术的产物，自然地镶嵌在阿姆斯特丹市中心的这座纪念碑中。

The dome on the roof is based on the Gridshell principle, which offers enormous freedom of design and allows large spans. Parametric design principles were employed to create a light and transparent dome, with no two components being the same. The High Light is a self-assured statement that defines the project’s face yet maintains a respectful relationship with the monument. The special spatial experience of the glass dome, as a product of the latest design methods and techniques, is naturally embedded in a monument in the Amsterdam city centre.
