FURNITURE: DIY, a tub plus patio table glass = cool side table! Great idea for patio; use removable plexiglass top, and use the tub as an ice chest. Also, can paint the tub to match the Radio Flyer Wagon.
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.
