Since the beginning of human history, the geometric order and chaos exists in the architectural and urban structures together. In context of future dissertation, this paper presents an opinion, that for a good quality of architectural space the balance between order and chaos is necessary. The architectonic space is created by design and other self-organising processes as well. In the long term it is unforeseeable and unstable. The development of the chaos theory creates a new perspective for better understanding of chaos and complex processes in architecture. Some aspects of this theory can by applied in design.
