Architect Greg Zahn wanted to honor his grandfather’s woodworking legacy by building a Cordwood Tool Shed near Manitowoc, Wisconsin.  He asked if Cordwood Construction Resources LLC would teach an onsite workshop and we jumped at the chance.  Photos & video are below.  Greg Zahn 4

Beautiful recycled glass bottles make for a colorful glass display.  Note that some of the colored bottles are placed on the outside.    Greg Zahn 5

Tools of all shapes and sizes were embedded into the walls of the aptly named Cordwood Tool Shed.
