I think my ideal living space is part greenhouse and part library. To get the look of the latter you don't have to have a wheeled ladder — just orderly bookshelves.
A well organized collection of books (and even some no-maintenance trompe l'oeil wallpaper, Image 8) can look good in any room. Done right, even your stairways can be book repositories (Image 9), and your bookshelves can double as room dividers (Image 7). Try going tall to add drama and maximize space, and for an extra punch consider dressing up the shelves with paint or paper.
