The relationship with the client is a permanent issue of the architectural profession. In this paper, real examples of commissions have been used to illustrate the most common oppositions, misunderstandings and confrontations that occur in the course of such a relationship, using never published before stories of architectural commissions from the history of post-war Greece. Using original interviews of some of the most important Greek architects of the last half a century, famous problematic commission stories from the international architecture scene and texts that provide a theoretical background to this subject, an attempt is made to thoroughly analyze this relationship and to attain a more complete picture of its dynamics.
