Fully Customizable Built-in Pizza Oven
Made by Fiero Casa (the company that makes the oven that Roberta's pizzas are cooked in) this oven is fully waterproof and ready for you to build into your custom outdoor kitchen. They also suggest building the oven into an exterior wall and having it open right into your indoor kitchen.
With its basic boxy shape, we could see installing this into a wall lined in coreten steel with a box built in below for storing your firewood (although you can also get it as a propane or natural gas oven).
It comes in two sizes (duo or quattro) for cooking 2-4 12" pizzas at once this is an awesome way of getting a professional grade oven with a totally custom and built-in look. The supplier also offers free pickup in Brewster, NY.
