Farab Co. Office’s entrance shines with two copper-colored plates on the door where the icon of the sun is deleted from the plates, and the shadow that is formed creates a pleasant atmosphere. The use of copper color and its luminance in the space, as well as the repetition of the sun pattern in the lobby and the corridor’s floor, actually emphasizes the energy and the sun in our design concept for a company like Farab, which operates in the field of renewable power plants.
