Reversible Destiny Lofts (Tokyo/ Japan)

"Most people, in choosing a new home, look for comfort: a serene atmosphere, smooth walls and floors, a logical layout. Nonsense, says Shusaku Arakawa, a Japanese artist based in New York. He and his creative partner, poet Madeline Gins, developed a small apartment complex in the Tokyo suburb of Mitaka that is anything but comfortable and calming. "People, particularly old people, shouldn't relax and sit back to help them decline," he insists. "They should be in an environment that stimulates their senses and invigorates their lives." "
