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.
Fun Out door space with bar and sunroom. Glass garage door lets the outdoors in when cold months are on us and it can be opened in the warm months. Bar also closes and opens with hinged swinging doors.
