Bau is a design handle born to enhance the dialogue between materials of different natures. The meeting between metal and a noble material like marble generates a refined, essential and strongly architectural contrast. Inspired by the principles of the Bauhaus, Bau adopts a pure geometry and technology reduced to the essentials: drawn brass and marble come together through a precise and elegant joint. A window handle with exclusive appeal, capable of transforming the functional detail into a distinctive element of the project.
