Diagonal Zero Zero, High-tech office tower in El Besòs i el Maresme, Barcelona, Spain.
This 110-meter tall skyscraper features 25 above-ground floors and a distinctive trapezoidal design with a glass curtain wall and aluminum profiles, serving as Telefónica's regional headquarters in Catalonia.
Completed in February 2011 after construction began in April 2008, the tower was built using advanced formwork systems including ULMA's Climbing System 2000 and employed over 450 workers during peak construction periods.
Designated as a Cultural Asset of Catalonia, the building represents the evolution of contemporary Catalan architecture and serves as a symbol of technological innovation and urban development in the region.
Located along Barcelona's Diagonal avenue with access to public transportation, the building houses six elevators serving its 30,000 square meters of office space and includes three underground levels for parking and services.
The tower's tube-in-tube structural framework incorporates a central concrete core surrounded by steel perimeter rings, allowing for column-free office floors and exceptional resistance to wind and seismic forces.
