Build simple plywood forms, mix and pour your own concrete to fill them, and then install this outdoor bench in your favorite garden spot. You can follow the plan exactly as shown to learn the process and then experiment with your own shapes and designs to create a variety of garden benches. The concrete forms for this bench are not only cheap but also reusable. You can create at least five concrete benches from one set of forms. The concrete bench details come from panels built into the forms that appear as recesses once the form is poured. Add unique personal design with tile, stone and more and then sit and enjoy it for a lifetime. Build this three-piece concrete bench a little at a time over the next week.
