The planes are elevated so that the horizontal parts of the protostructure won't interfere with the view. This levitating planes are disposed on different levels so that the view is directioned either straight (white) or downwards (orange), therefore creating the illusion of the two different existing but non apparent floors. The difference of color signals the two different views and points of view, this creates a distance between them while at the same time indicating the same view but in different colors.
The illusion was all a result of the research in drawings. The perspective was the one that indicated at which height each plane should be for the view to work (the point of view was dictated by the height of an average human being), then the Monge projection shows how the planes are integrated to the protostucture and how to adapt it in order to make it stable. Finally, the axonometric projection gives a general view of the finished project.
