The space of construction a certain place has been formed by the fact that it is divided into the external space and the internal space (territory) by the material boundary of the roof and the wall open part etc. Shape has occurred in the building as a substance, the building contour which forms the boundary aspect inside and outside directly is a relationship. Because of that, the designer changes relationship by the construction contour and the fact that form of the inside and outside space is operated. In addition, as a use there is a function in the space in the building, the functional segmentation of the internal space and the external space has occurred with the segmentation. You can do the arrangement of the space where it corresponds to the respective function in those, furthermore in the material boundary the various elements which respond to function exist. We use the concept of interior/exterior that internal space and the external space and boundary are caught continually.
