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 produces a refined, essential and strongly architectural contrast. Inspired by the principles of the Bauhaus, Bau adopts a pure geometry and a technology reduced to the essential: drawn brass and marble join together through a precise and elegant interlock. A window handle with an exclusive taste, capable of transforming the functional detail into a distinctive element of the project.
