You want a workspace that is big enough to spread out on but you don't want your small office to be overtaken by a monolithic desk. Mount your work surface to the wall for a lightweight and "floating" desk.
Unpluggd reader Deborah has a small apartment and a home office that serves double duty as a bedroom. She didn't want to block the great view and the natural light coming in from the bedroom windows with a huge desk but she did want a nice long workspace with plenty of room to spread out. By mounting a sturdy floating shelf as a work surface she created a spacious area with room for a television, office supplies, laptop, and writing area.
