As any animal we are afraid when we cannot position ourselves. A successful building is one that does not need directory. One should be able to perceive the logic of the structure and go with the flow. There is a great sense of comfort created by a clearly ordained structure. Some round buildings are difficult to maneuver as it is hard to understand where you are in relationship to where you started. Some building types might be better if not understandable and full of surprises. But this is not the norm apparently. It seems important as to the sense of scale, straight lines are easier to evaluate than curves. One reason why the Harbor cities are always quite pleasant, is about the structure defined by the focal point that is the Harbor. Even better if the site is hilly as immediately one can memorize sites and vistas. Sydney, San Francisco, or even Rome withe the seven hills.
