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.
If you’re low on square footage, a wall-mounted desk or built-in work surface can be a great space-saving solution, providing roughly the same work area with a smaller footprint. See our favorite wall-mounted desks now.
