Fold down garage workbenches. Space saving. Cheap. Used doors as work top. 2x4 screwed to wall. Door hinges attached to doors and 2x4. Angled pieces swing out on strap hinges to support top. A notch was cut in so they fit around the 2x4. Later I laminated the work surface.
Iron strap hinges and tall escutcheons backing the doorknobs on a set of double doors imparts an old-fashioned, barn-like look to this front stoop: http://www.bhg.com/home-improvement/door/exterior/farmhouse-front-door/?socsrc=bhgpin043014hardcorehardware&page=5
