In this composition, main concern is different openings which creates different spatial relations. For example in the specific location, a visual opening reacts as a accessing opening like windowish. Or a space between two big box space like a topographical features, creates a path which has relation with another accessing opening. Therefore a path reacts as transition space. Additionally height differences between spaces used as a architectural element and relations with some visual opening which reacts as a accessing opening and, this is also doorish,windowish in my opinion. Or in the two specific spaces, a mass and visual openings creates two sub-spaces in the single space.
