The complex was one of the largest projects in the world which integrates artwork into the architecture. Mérida received the commission in 1951, which took him three years. The murals covered an area of 4,000 m2. This project would become the most sophisticated realization of the concept in the post World War I period. Another example is the underpass walls along Orizaba Street. Mérida realized that motorists did not have time to contemplate peripheral images, so he placed elongated anthropomorphic figures which preceded and anticipated the forward motion of the cars. Each legend was depicted with a series of figures nearly eight feet tall each, which tell the story in frames as one ascends the stairs. The figures were chipped from the concrete in bas-relief then painted. Pani's and Mérida's work received mixed reviews, which often reflected the rivalry
"Contemporáneo" school of art, and the more politicized
Mexican traditional muralist movement. There was also reluctance to accept Mérida's work as "Mexican" as he remained a Guatemalan citizen his entire life. One example of this mixed message was from
Siqueiros, who initially praised the "plastic integration" concept but then condemned both the art and the architecture as "bourgeois", poorly done and representing a return to the pre
Mexican Revolution Porfiiran era. While Siquieros criticized Mérida's work as something attractive for tourists, in the following decades it would be Siquieros' work at the Ciudad Universitaria that would draw tourists, leaving the work at the apartment complex forgotten. ==1985 earthquake==
