The construction process was based on the original building designed for the newspaper La Nacion nearly half a century ago. It was a strong structure capable of supporting the rotary printing presses installed in the lower levels, and the linotypes and editorial offices located on the upper ones. When the paper's press plant was moved into a new building, an important and valuable amount of space was left vacant.

La Nacion's directors decided to keep the headquarters in the building, but asked HOK St. Louis to design an office tower to be built on top of the existing structure.

The original six-floor building was used as a foundation and wrapped up into the new tower's curtain wall that rose with vertical and curving surfaces resembling a cut crystal. The resulting building has 65,000 square meters of floor space. Sixteen new floors were built for flexible office use.

The building is located in the new East corridor between the fashion urban development Puerto Madero and the Buenos Aires financial district. The east façade gives character and identity to the project, offering a view of the River Plate. The west one offers large vistas of the urban framework.
