This grey living room with floor to ceiling bookcases uses a very uniform shelf structure but displays the books themselves in a random, jumbled way, creating a unque and interesting feature wall
Wow! This is gorgeous. Notice how it is created, the top is flush with the wall and the bottom stands out - just how a picture frame would be if you leaned it against the wall. This uses the ladder type idea.
