BARCELONA (ES) - Torre Diagonal ZeroZero in Barcelona is the striking headquarters of the Spanish telco, Telefónica. The 110-metre-high tower, situated on Barcelona's main avenue, the Diagonal, catches the eye with the dynamic play of diagonals that criss-cross its facade. The overall effect is reminiscent of the polished facets of a diamond, an image that is strengthened by the brilliance of the glass.
The facade is a modular curtain wall made of white aluminium profiles and (transparent) glass with white ceramic paint serigraphy. The vertical pattern of the paint reinforces the slenderness of the building and, in combination with the internal column structure and the exterior structure, contributes to the diffusion of daylight and to glare control, generating a pleasant working environment with great views.
