While grills are still the dominant outdoor cooking species, there are other appliances to help you achieve outdoor kitchen nirvana. Outdoor kitchens can be as big or as small as you prefer. If you are planning a permanent outdoor kitchen — one with an island where a grill, warming drawer or oven can be built in — you'll want to take into consideration the sizes of the appliances before you begin building.
Baking outdoors? With today's outdoor wall ovens, as well as stone hearth and artisan ovens, you can bake fresh bread right next to your grilled salmon. A built-in outdoor convection oven will typically be around 18 inches wide by 18 inches deep; expect to pay about $2,000. Designer Ann Porter, of Kitchen Studio of Naples in Naples, Fla., points to pizza ovens as a "must-have" item for the outdoor kitchen owner who has it all: "These ovens are great for entertaining small crowds or large parties."
