Smart shelf in solid wood, fully customizable increasing width or height anytime, creating new storage compartments to store books and other decorative items.

While it looks like any freestanding bookshelf when collapsed, it actually consists of two intersecting bookshelves of the exact same size, allowing you to simply pull the other one to the double your storage facility. The second bookshelf can also be expanded upward, partially extended to either direction, and even tilted if you want a more avant-garde aesthetic.
