The Concrete Countertop Institute is offering fire pit designs in Crater and Ridge models. The plans for each design include detailed cut sheets and assembly instructions at a level of detail that stretches to 30 pages. The plans are meant to be used with glass-fiber reinforced concrete, but they could be adapted for other casting techniques.
Fishstone offers the plans and sells all of the hardware needed, such as burners, starters, fire glass and lava rock, in convenient Crater and Ridge design kits.
