I bought a used, recycled satellite dish from my neighbor to use as the top for a grape-arbor gazebo. The gazebo legs are warehouse storage-rack legs (which I also bought from my neighbor), but you could use any kind of wood or metal pipe.
I used three-quarter-inch conduit as braces, cattle panel fencing for the railing, and 1-inch plastic pipe to top off the railing. I painted the whole gazebo black to give it a unified appearance. Use materials you have on hand to personalize your gazebo.
