In an interview with Gregor Schneider he says that:
“For me, the most important technique is to build a replica of a room inside or next to the existing room. I build a bedroom in a bedroom, a kitchen in a kitchen, a childrens’ room in a children’s room…… I have been doing this until today.
These are not architectural spaces, but are facsimiles of rooms-within-rooms in the existing house, created as artworks. For me the most important thing is to create a complete replica inside the existing room. I don’t just split the rooms, but I duplicate all the rooms, including walls, floor, ceilings.”
And there is a room called 《KAFFEEZIMMER》=TURNING COFFEE ROOM. This room has an invisible rotating mechanism built into it, and it makes one revolution while visitors sit down and have a cup of coffee. But the room rotates so slowly that when they leave the room, they don’t notice that they rotated once right round.
He also constructed a “dead space”, just like constructing a bed room, a kitchen or a bathroom.(Like my vantablack room ) A “dead space” is not a special room, but a room that exists just like other rooms.
He also explains that Construction is a way of getting close to the unknown
” I created a work 《CUBE》inspired by the building in the Kaaba. Through this experience, I could have a physical experience of standing in front of the black stone. This is how I approach things that are totally unknown and un-comprehensible.”
