A major impact on Andreou's method of expression and in the development of his personal "language" was his friendship with Le Corbusier. They first met in 1947 and worked together on and off until 1953. At one time Le Corbusier asked Andreou, "Where did you learn how to work?" to which Andreou responded "I'm Greek, I carry the knowledge within me." This friendship instilled in Andreou Le Corbusier's view of architecture as monumental sculpture and, conversely, sculpture subject to the laws of architecture.
