18 architects and designers worked together on Hotel Puerta America in Madrid.

On the twelfth floor, Jean Nouvel decorated twelve suites with images that evoke the human body or nature. They are reproduced on vertical panels that slide on guides to permit guests to reorganize the various zones of the suites, the bathroom or the living area, according to their own requirements of space and taste.

The pictures of photographers Nobuyoshi Araki and Alain Fleischer come alive only as night falls. The prints are on the reverse side of the canvas, and so invisible by day. But in the evening, they are backlit by LEDs and become visible.

More images: europaconcorsi and El Mundo. Don’t miss the underground parking by Teresa Sapey.
