If you like to cook for friends and family and enjoy being outdoors, you may want to indulge both passions by building an outdoor kitchen. Outdoor kitchens typically are comprised of permanent counters and built-in equipment. Outdoor kitchens can include grill, separate cooktop, warming oven, refrigerator, sink, etc. Of course, this equipment requires utility hookups, such as electricity, water, and fuel (propane or natural gas).
