The process of learning has three phases:

I Mould: carving of the architectural space;

Il Figure: the positive of the carved space seen as an independent object;

III Wall: unfolding of the vertical volume of the mould and folding it into a new spatial organization. 

“This choice seems to repeat the dialectics of the hylomorphism, the architecture caught between the mould and the material. But that initial binary relation is developed through the consecutive steps of the different spatial-material states of an architectural project. From a mould which is carved, through a figure which is cut off from the background, to a wall which is unfolded and folded into a new spatial configuration.“
