The project for the facades of Barcelona World Trade Center, configures a set of four buildings, rising ten floors above ground level with a circular ground plan looking out in all four cardinal directions. Enclosed between them is a space that is open on the ground and first floors, forming a large central courtyard used for the common services and activities of the complex.
The interior façades enclosing the central courtyard are vertical, while the exterior ones have an inclination of 75 cm on each floor, giving the overall volume of this complex the form of a truncated inverted cone simulating a large moored ship. The project is based on an imaginary cubic modular mesh measuring 75x75x75 cm, applied with maximum rigour. This modulation, further complicated by its sloping circular surface on the outer walls, is nevertheless respected in the breakdown of the panels by means of real or simulated horizontal joints that coincide with the mesh.
