I see a lot of "almost" bookshelves. They hold books and look "design-y" but they waste energy and space. If you are really into books, it's not about the cute shelves. It's about the books. Make that space hold as many as it can.
Já tinha visto em Milão em 2013 na Boffi. CTline bookshelf designed by Victor Vasilev. From a particular angle, this construction looks nothing like a bookshelf, but rather a minimalistic art installation.
