A roundabout is a good way to add levels of vertical interest to garden arbors. A roundabout is an arched trellis that can provide support for climbing plants, shade during the hottest hours of the day or a nice focal point when used with flowering plants like bells or clematis. Make your hardware or plumbing supply cut PVC pipe at the correct length. In an open expanse of ground, lay out all your pipes and pipe fittings. Mount support the gazebo by installing three pieces of 2 feet of PVC pipe, along with two of the fittings of five ways. Secure the pieces glued using PVC cement. Repeat this step four more times for the remaining supports.
Connect a 45-degree elbow to the top of each support. Turn the joint in place so that they face what will be the inside of your gazebo and garden arbors. Mount the arch connecting two elbow joints 45 degrees at the ends of 1 foot piece of PVC pipe. Attach two pieces of 1-foot pipe at the other ends of the joints. Repeat this process to create a second arc.
Each arch supports two of the arbor by inserting the ends of the arc on the boards of 45 degrees that sit on top of the brackets. You should now have two halves of your entire gazebo. Insert the remaining four pieces of 1 foot long PVC pipe into four five-way meetings of its arbor halves. Place the remaining half garden arbors by inserting the other ends of 1 foot long PVC pipe beams in the five-way joints of the remaining half gazebo.
