The green design strategy that involves both horizontal and vertical green was to generate a gradient that fades from the lower part, in which the plant essences have a shielding function and for this are evergreen, to the upper part of the building characterized by species mainly deciduous that offer a change of seasonality and whose transparency emphasizes the theme of the view on the panorama of Rome. The vegetation gradually becomes more and more variegated and flowery acquiring an increasingly Mediterranean character typical of the Roman territory.
