In a hall for the production of building materials, a design was required which would not only allow an efficient arrangement of all the necessary functions for individual production sequences, but also create a structural shell capable of bearing the corporate design of the company. The design responds to the height graduation of clearly distinct functional areas through the optical intertwining of two structural volumes. The two bodies differ both in their color and façade structure. Connecting elements are vertical strips of glazing, which, to provide variety, begin in one structure at the ground level and, in the other, extend to the parapet. The smaller cube rests on a circumferential base which rises into a section of wall at one end, signaling the direction of a new office building which will also be constructed.
