I want to build a fireplace outside. I have no worries about catching anything on fire. I will build the firebox out of firebrick and refractory mortar. I would like to know if I can build the surround, throat ,smoke chamber and flue out of cement board and steel studs? uhhhhh, if I do will it last? Most likely I will build a few fires a year. The exterior will be stucco.
:huh:
