Concorso City Vision, Roma

The volumetric articulation of the proposed building is obtained through the modeling of its masses and the use of two different building skins. These establish a continuous architectural dialogue between internal and external parts. The inner volume is finished in a sharp glass surface, while the external one is in granite. The glass tower is inserted inside a rock well anchored to the ground. The glass volume is intended as a monolith: an enormous, bright and almost immaterial element set in the granite crust from which it emerges. The image is that of a "glass-sword", frozen inside its mold, irreversibly set in an articulated and dissonant unique whole, where different characters coexist in their diversity. A centrifugal motion continually disturbs the two hexagonal volumes, with frequent prolongations of parts of the glass into the granite, whose surfaces assume different thickness and acute angles (60°). The geometrical rules upon which plans are set are based on the equilateral triangle, generating the grid from which two regular hexagons are extruded.
