The project at Kap 5, an office building designed by Barkow Leibinger, explores new avenues of flexibility in the workspace where interior and lighting play a fundamental role. With the boundaries of social and working spaces in the office ever dimming, the task for this project was to design a lighting concept that provides suitable light for a workday, which can take place anywhere from a desk, coffee room or couch. Likewise, the building consist of three parallel slabs, offset and staggered in height, all boasting an impressive glass facade, challenging the publicly exposed light concept to take into consideration both the utility indoors and its aesthetic contribution to Hamburg’s urban landscape. Integrated lighting fixtures embedded in the acoustic ceiling, as well as controlled glare-free micro-prismatic optics, provide an exceptional and comfortable office space that further serves as a lantern of sorts from the outside.
