South Korean artist Choi Jeong-Hwa created this 10-story art installation made up of 1000 used doors.

From an interview at the Creators Project:

I attended Hongik Art School and started painting there. Around 1986 or 1987, I entered a contest and happened to receive the grand prize—a ticket to Europe. Basically, I made the paintings I thought they’d like in order to enter the contest and travel to Europe. When I returned, I burnt all my drawings and decided to never paint again. I accomplished my goal of winning a trip to Europe, but I was ashamed, and decided that from that point on I would use my work to portray only the things I truly felt. For example, I think construction sites are rough and alive, but I don’t want to paint them because I can’t seem to express those feelings in two dimensions. After I made that realization, I started to pick up things from the street and take photos of them.
