Japanese firm SAKO Architects designed this whimsical children’s bookstore called  Poplar Library in Beijing. Entitled Kid’s Republic, the store features two rainbow  ribbon pathways that float over two floors where children are invited to explore the wonderful world of books. Cozy corners and open spaces fill the store. My favorite features are the holes built into the bookshelves that convert into little lairs to read in, and some act as secret passageways into other sections of the store. It’d be hard not to have a good game of Hide-and-Seek at Poplar Library.
