Main functional and morphological element of the composition is the closed public waiting area expressed in the form of an internal walkway from which are hinged the individual modules. The pedestrian is progressing freely as a natural continuation of the street and through the transparency, the city pictures penetrate the body of the building.
The route of the walkway is clear, not perfectly geometric. Variations of the side limits impart throughout the building a sense of motion.
The volume of the linear building along the northern boundary of the site, formulates with clarity and balance the number of heterogeneous parameters entering in the composition.
