Creation of two spaces separated by the mould, like a wall. Two differents planes built this two spaces, one is horizontal and the other is tilted, which comes from the two slopes of the mould.
Depending where you are, you can have a sensation of stability, or a sensation of loss of balance but in both spaces you see orthognonal planes.
Situation of the mould and the origin of the tilted plane
Monge of the two spaces [1:33]
Differents possibilities with the planes and the +column.
Idea to incline the +column perpendiculary to the tilted plane, changing the point of reference for the tilted plane and creating a different balance for the column.

The two spaces, and the only passage to connect them is through the threshold of the mould.
