CIRCULATION

When it comes to circulation the architect has very diverse ways to achieve it.  In vertical circulation he uses a lot of ramps because he's really interest in making a recognition of the spaces and a ramp gives much more of a slow way to enjoy the amazing spaces that he creates.  It's a way to make sutil the transtition of one place to another .

                                                                                                         

In general i think Niemeyer preffers horizontal circulation because it gives a longer tour of the buildings, in this last example we can see that is a vertical building but the main circulation point, the first floor, is a walk with complete horizontal circulation for a better apretiation of space.
