Freestanding Outdoor Pavilion structural design Needed

I am constructing a freestanding pavilion-style roof constructed to cover an outdoor kitchen area in the 28117 ZIP code of NC. I need a structural design of a full cantilevered roof, or a partial cantilever. I am trying to minimize the typical 3rd and 4th corner post to allow foot traffic. I am fine with a design as seen in this pic, or close to it. The dimensions for this covered area are 224 inches wide by 160 inches in length. I am open to using either pressure-treated wood or metal for the structure, depending on what is most suitable and cost-effective. The pavilion should be durable, visually appealing, and provide ample protection against the elements. Ideal skills for this project include experience in outdoor construction, expertise in building freestanding structures, and knowledge of materials suitable for pavilion-style designs.
