The author of the article first presents the factors affecting the formation of a Prehistoric settlement and of architectural structures in general. These factors, through their application, refer to the organization of space, to food-supplying and ideological inventions.

In the process,the author attempts to analyze ways through which these inventions affect the Prehistoric habitation and concludes with a proposal referring to distinctions between forms of Prehistoric habitation. On the basis of this proposal the author distinguishes two basic forms of Prehistoric habitation: (a) the single-space and simple one, and (b) the multi-space and composite one, which appears in two versions, the megaroid house and the megaron. The article presents sound descriptions of both kinds of houses, analyses the reasons for the invention and construction of the megaroid type and comprises all the theories on the origin and character of the megaron.
