The district plan confer a singular role to this block and his top specially. A "cylindrical volume" is defined to establish a milestone in the planning of the space. The regulation fosters the breaking of the uniformity, not only in shape and height but also in façade finishing. To enhance the "milestone", a treatment based on ventilated façade has been foreseen, with ceramic pieces, matte finish, in vertical component and modulated following the window hollows. To obtain a certain forcefulness result, it has opted for a tilted top of the cilindrical volume with "bow" to the east. It aims to achieve a formal contrast in texture-shaped between the "cylindrical volume" and "lower body". Treatment of bricks in the "lower body", extends to the "cylindrical volume" through the ground floor so that visually link both bodies.
