Regardless if a patio is round, square, or other shape, concrete pavers are a common and popular choice for floors. And generally because of either lack of materials, education, or paving skills, a basic running bond pattern is used on most patio and courtyard designs. Some folks don't even realize there are other paver patterns like this one available. See floor paving patterns for a few design ideas and patterns. Especially if you're creating a circular patio like this, this may just be one area where your patio budget would allow for a hired contractor to do the work.
