Foster + Partners has revealed designs for the headquarters of RMK, one of the world's leading copper producers based in Yekaterinburg, Russia. The 13-story building is designed to complement the company's working style, splitting office spaces into two-story modular units which provide comfortable and flexible work spaces.

The facade of the building features triangular panels of bronze-colored steel, a motif that is inspired by the color and chemical structure of copper. These steel panels also express the modular offices within the building, with each ten by six-meter panel corresponding to a single office module, and regulate the building's temperature by shading the building in the summer but admitting winter sunshine.
