The best way to increase the amount of floor space in your garage is to get the items on the floor up on the walls or ceiling. The best way to do this is with a Slat-wall system on the walls that can accommodate an assortment of baskets, brackets and wall storage tools that can fit on different areas of the wall and can be slid along the wall or set at different heights. Overhead racks is another way to get these items off the floor. a 4?x 8? rack can be anchored to the ceiling and drop down from there and provide a ton of extra storage with an area that before was just dead unused spaceā¦the ceiling area. The taller your ceiling the more storage you can get. Check out the storage gallery to see some options and get some ideas.
