The first bay of the building section is preserved and reinforced with a series of concrete walls, a new covered courtyard was made, which holds a new elevator to access the upper levels and terrace. Most important, the roof terrace was transformed into a restaurant overlooking Templo Mayor and the rest of the historic center. The 1960s building was re-cladded in a red aluminum, which gives visual uniformity to the building and merges with the color of tezontle, used in the surrounding historic buildings’ façade.
