"Berlin" were developed in close cooperation with two German traditional companies: Kaufmann Keramik and Brunner Kachelöfen. They reinterpret tiles covering traditional ceramic heating ovens. Their three-dimensional form increases the surface area, allowing the oven to give off more heat. The interplay between different optical structures and materialities on the surface of the oven is the crucial design element. Viewed up close, the geometrical pattern resolves into a fine structure of dots.
