Backyard fire pits are great but can blow smoke in your face. After building a smokeless fire pit a few years back, HAXMAN wanted to make a new version for his patio out of concrete. He bent sheets of XPS insulating foam to create two forms, then filled them with concrete. After building the structure, he drilled holes into a metal fire pit ring for ventilation.
