I have steps in my garage that lead to the basement. I would like to use that area in the winter to store my lawnmower, motorcycle, and snowblower. How can i put in a platform to hold these things over the stairs.. make it strong enough, and then be able to lift it so the stairs can be used in the summer? Looking for input on doing this and being able to lift the platform by a pulley and attach to the garage wall when not in use. What would I all need in the line of tools to complete this? Thanks in advance, Terri
