Purist design language and crisp, graphic lines are the hallmarks of pieces in Kollektion Witulla. Jennifer and Natalie Witulla first started collaborating on designs and projects when they were studying industrial design at the Art Academy in Kassel. During that time, they also gained their first professional experience. After graduating, the sisters worked for various companies and studios in Berlin, where they also set up their own design studio. Creating durable, timeless objects is their credo, and metal, glass and stone are their preferred materials, as they allow precise designs with smooth surfaces, clear contours and a strikingly sleek aesthetic. For Schönbuch, Jennifer and Natalie Witulla created the minimalist coat rack KAMI.
