Comparing the relationship between Venturi's residence, Villa Mairea, and Villa Mairea with the orthodox modernism, Aalto and Venturi denied the sterility of modern architecture in Orthodox churches. This rejection brought about the development of postmodern in architecture. Both architects believe that an orthodox modernist ultimately produced a design made of glass or white box, as well as a desensitization of human size and shape. The concept of modernism, that is, the form following its function is contempted by Venturi.
Vanna Venturi House (1962 - 64) of Robert Venturi described in detail the purpose of postmoderns to convey meaning and symbolism. According to Venturi, the exterior is a symbolic picture of a house dating back to the 18th century. This is accomplished by using symmetry and arch at the entrance. Perhaps the most ironical example of post-modern architecture is Charles Moore's Plaza of Italy (1978). Moore quotes the elements of Italian Renaissance and ancient Rome (architecture). But he did this. It is ironic when people notice that the pillars are covered with steel. He cited an ancient Italian way away from the original New Orleans.
Perhaps the most famous building at Venturi is his mother, located in Chestnut Hill, Pennsylvania, his home designed for Vanna Venturi. (1962). The goal here is to create a building that functions both artistically and artistically. For this purpose, the architect blended contradictory features: the shape of the house was simple, but the internal plan was complex; the overall front was symmetrically imagined, The size of the house is small, but details (door, chair rail, mantle) are many.
