“The ground floor has few windows and a low ceiling. Intense rays of light will penetrate the dark. It is the perfect atmosphere to erect white stone arches: they will emerge as architectural ghosts and their number should be sufficient to give an impression of movement and circulation to the piece.
The stone will be the same as the one used for the Sentinels. White and alive, in the light and space of the building. I like the idea that the Sentinels shall be the guardians for the arches.”
