It is possible to build a partially brick oven. The reasons vary; you cannot afford the materials for a full-on brick oven, you like cob ovens but want to strengthen the mouth and provide a chimney, or some other local material could also work.
I have encountered and worked with these variations.
Cob ovens, made from a mixture of clay, sand, and sawdust are very economical, easy to build, and moderately durable. The fire exits the mouth directly and the oven needs shelter to protect it. The cob oven's mouth is especially vulnerable and there is no chimney to direct flue gases away from the user. Enter the Hybrid. A brick mouth, face, and flue enabling a chimney to be attached.

- Other materials may be available. A couple of years ago I built an oven in Mexico using raw, unfired adobes. In some locals, there may be reclaimed red-brick, cut stone, etc. Castable refractories, though expensive may simplify the process.
