This generous interior public space of an office building shows the need of expressing architecture in terms of pure space: all elements have been placed in a rational but free way. The transparency of the hall is expressed in the courtin-wall and in the dominating verticality which goes up through the ceiling's gap. Structural forms fill the borders: triangular large pillars and flat platforms at the left, a textured wall at the right. The simple profile of the mountains behind the glass points the romantic and detached condition of the site.
