In accordance with the author's theory of 'architecturally defined space' (ADS), according to which architecture consists of four basic elements - environment, man, boundaries and perspectives - the topic of 'introverted and extroverted architecture' is a topic immanent to architecture, since the terms 'introversion' and 'extroversion' are one of the main characteristics of the personality of every human-individual. The personality of the human-individual, both the client for whom architecture is created, and its creator - a trained architect or an anonymous craftsman - is directly reflected in the physical appearance of architecture. Introversion or extroversion in architecture is also a more or less direct consequence of the influence of other fundamental elements of architecture - the natural and social environment and the element of perspective. Just as an individual human cannot be classified exclusively as an introvert or extrovert, architecture can also, at the same time, have the characteristics of introversion and extroversion. In this regard, it is not possible to prefer introversion or extroversion, neither in the individual human nor in architecture. The world is full of extraordinary architectural achievements that are predominantly introverted or predominantly extroverted, as well as those that are both. Also, the terms introversion and extroversion cannot be tied only to one (any) architectural program, nor to one historical period or culture. Since the house (or rather the house complex) is the closest and most immediate framework of human life, extroversion or introversion can be read most clearly in this architectural program. The treatment of the topic 'introversion and extroversion in architecture' will further shed light on the complexity and controversies in architecture and be another contribution to the explanation of the author's theory of architecturally defined space.
