You can build adjustable utility shelves in a single afternoon using 2 × 4s and plain 3/4" plywood. Perfect for use in a garage or basement, utility shelves can be modified by adding side panels and a face frame to create a finished look suitable for a family room or recreation area.
The quick-and-easy shelf project shown creates two columns of shelves with a total width of 68". You can enlarge the project easily by adding more 2 × 4 risers and plywood shelves (do not increase the individual shelf widths to more than 36"). The sole plates for the utility shelves are installed perpendicular to the wall to improve access to the space under the bottom shelves.
