In accordance with the theory of "Architecturally Defined Space (ADS)" - Environment. Man, Boundaries and Perspectives - The author of this paper was mainly concerned with the relationship Environment - Man, Boundaries - Man and the perspectives of architecture. In this paper, the focus is on the relationship Man - architecture. In this case, Man is the client of the job (mainly for his family house) and Man is the creator of the architecture (mainly a trained architect, but also a 'folk craftsman following tradition'). In order to reexamine this relationship, the author analyzed well-known international architectural competitions. In the case of empirical disciplines (mathematics, physics, chemistry, for example), each person will solve a task with the same result as another, while in architecture this is not the case - there will be as many different solutions as there are 'task solvers'. In this way, Man, as one of the fundamental components of architecture, generates diversity and complexity in architecture, in a similar way as the Environment (natural and social).
