How to Build a Less Boring Glass Box Office Tower

These two photos feature Cube Berlin, located on the same plaza as Berlin’s central train station. The architects, 3XN, used reflective glass installed at various planes in their curtain wall design. So instead of a boring glass box, it gives facades that change based on the angle you approach the building. Structural engineers, Remmel + Sattler, used curtain wall construction to support the building structure and the exterior “skin”. In curtain wall construction, you move the columns away from the exterior creating a simple overhang floor structure that supports the exterior finish of the building. This allows for a more open view from the inside of the building and more freedom on how you enclose the structure. It works just like the wall bracket in your home that supports the curtain rod, which in turn supports the hanging curtain & drapes.
