Abstract
When one speaks of space in architecture, one immediately thinks of an entity that is an enclosed space. For most people , space is therefore equated with interior space. And in most discussions of architectural space the character of the outside and that of the inside have been strictly differentiated. But architectural space must be construed as a total , integral space. In this way , architectural space can articulate naturality. For example, by reasserting the eloquence of architecture and by graphically characterizing the different parts of the building. Ungers has moved far away from the traditional ideas of a modern movement that preached the homogeneity of all parts. so promoting uniformity and an expressionless monotony. From this perspective comes the purpose of this study which is to present :1. the character and meaning of the boundary that differentiates the outside from the inside of the architecture. 2. the types of the organization of the interior-space and the differences between those types. 3. the new concept of the interior -space through the analysis of the concept "Haus im Haus" that over-comes the polarity of the outside and the inside of ar-chitecture. This result comes from the idea that harmony is a-chieved not by resolving this polarity into one or the other extreme, but by allowing coexistence of both as-pects.
