A house made of books? It has to be a library. Sure, but Lacuna project is more: it is really a building that has been constructed from books.
Lacuna is an art installation constructed from 50 000 books. It is also a library where people can walk in, browse the bookshelves, and borrow books. Since the walls of Lacuna are made of books, the building will change as people take and return items from shelves.
The building will open at the Bay Area Book Festival in June 2015 in Berkeley, California.
