One of the characteristics of the House, built on two floors, is that it basically constitutes a square inside which a circle is inscribed that forms the plan of the cylindrical courtyard. An evident reference to the renown oculus in the Bridal Chamber in the Ducal Palace, this circular opening allows to view a portion of sky, creating an effect of harmony between the solidity of the general plan and the infinite quality of the circumference which is the soul of the building.
