Isn't this neat? Called Citybook, it was unveiled at Milan Design Week by Mr. Less and Mrs. More — aka designers Ubaldo Righi and Antonella Di Luca. They based the bookcase's design on a previous project, which also used the house shape you see here. It's cool how such a simple shape can produce such intriguing design possibilities — the bookcase is modular, so all the pieces can be moved about and configured to your heart's content. For €3,900, you get 32 sheet metal "houses" and 10 bases in your choice of white or dark grey.
