高层建筑的楼层通常是通过围绕轴线盘旋上升的楼梯相连，但这里的情况则完全不同。三条楼梯形成陡峭的小路，穿行于整幢建筑，紧急楼梯井里的开放式楼梯上下运行。这垂悬式的楼梯连接所有敞式办公室的工作区。在这栋14层高的建筑里，用户可以随意选择任何楼梯去往各个楼层。因此，办公室独特的开放式景观将所有楼层的所有工作区域融为一体。在此景观之中，承重轴心既是连接的元素，又有着与众不同的特点。轴心逐渐挪移，楼面布局也不断显现。轴心的放置与组合在每一层都会有变化，反过来又导向另一个空间布局。非常朴素、经济的手法却生成多样、宽敞的空间，无须使用任何示意性特征，即可给人别具一格之感。

坐落于苏黎世湖畔的瑞士再保险公司的新总部，面朝老城区。处于瑞士再保险公司相互独立的新巴洛克风格的建筑群中，该栋建筑有些鹤立鸡群。在这座历史古城的尽头，建筑群连接了城市密集街区与相邻的公园绿地。

由于立面全是玻璃结构，从远处便可看到建筑内富有表现力的承重结构。顶层的混凝土承重轴心与外墙齐平。直径15厘米的实心钢制电缆支撑着悬臂式的楼面。因此，人们从工作场所便可眺望苏黎世湖与瑞士阿尔卑斯山脉。湖光山色一览无余。

The floors of tall buildings are ordinarily connected by flights of stairs that revolve on their own axis. Here, in contrast, three staircases form steep paths that run through the entire building. Open staircases climb up and down on the shafts of the emergency stairs. These cascading staircases link all the work areas of the open plan offices. Users can choose which flight of stairs to take from one storey to another in the 14-storey building. The result is a single, open landscape of offices that brings together all the workplaces on all the floors. In this landscape, the load-bearing cores are both linking and distinguishing elements. The gradually shifting cores allow for a continually developing floorplan. The placement and combination of the cores are modified on each floor, leading, in turn, to a different spatial layout. Diversity and spaciousness have been generated with great economy and simplicity of means, creating a distinctive impression without the use of any gestural features.

The new SwissRe headquarters on the shores of Lake Zürich look out onto the city’s old town. The slightly elevated building stands alone next to SwissRe’s likewise freestanding, neobaroque premises. At the end of the historical old town, the buildings mark the transition between the dense blocks of the city and the adjacent parks and green spaces.

The expressive loadbearing structure inside the building can be seen from a distance since the façade is completely glazed. On the top floor the loadbearing concrete cores are flush with the façade. Solid steel cables, 15 cm in diameter, brace the cantilevered floors, giving the workplaces an unobstructed view of the lake and the Swiss Alps in the background.
