Façade Stream Berlin

The “STREAM Tower,” which serves as an office and conference building, is located in Berlin-Friedrichshain, right next to the Mercedes-Benz Arena. The firm seele was commissioned to handle the detailed design and construction of the building envelope—covering approximately 13,000 m²—for the 97.5-meter-tall structure. Engelsmann Peters, as a subcontractor, handled the structural engineering for the element-based facade. The building’s floor plans, which vary from floor to floor, provide a high proportion of open space for occupants and are a key feature of the design. The facade design is based on a large number of individual element types, each engineered to accommodate the respective loads and dimensions. A distinctive feature of the project was the large-format elements, with widths of up to 2.70 m and heights ranging from 3.20 m to 5.20 m. In some areas, the aluminum frame elements incorporate reinforcement profiles that were integrated invisibly into the aluminum frames. The connection points between the facade and the building, as well as the joints between the elements staggered from floor to floor, were developed and optimized in close collaboration with seele.
The corner elements and the fastening systems for the cantilevered architectural elements also required special structural attention.
