Cubism
The idea of the façade is simple: take a simple image, divide it into equally-sized components, and reapply them to the balconies of this building. You do not see the image when you stand in front of the building. But in the course of several visits, as you walk up and down the street, you will see the various components of the image, divided over several balconies, come together as a complete picture, not so much with your eyes, but in your mind, rather like Cubism.
Found Object
In the course of several visits to the construction site, the idea of the "found object" came to light. Picasso was not only the founder of Cubism but also one of the pioneers of the use of the "found object" in collage and in sculpture. The "found object" is literally that: an object chanced upon in the streets and trash heaps of Paris during Picasso's daily perambulations: a twisted bicycle wheel here, a busted radiator there, that eventually ended up as a key element in a sculpture.
In the Main Lobby, the demolition process revealed traces of outstanding visual interest: the jagged edge of a demolished floor slab here, the texture of formwork on the underside of a floor slab there, that eventually end up as key elements of the space. Ordinary things seen in new ways become extraordinary.
