There is a round house in Mount Sterling, but it isn't actually "geodesic". It's an interesting octagonal design with square roof panels as well as triangular. I looked inside when the shell was up and the interior framing just in progress. I visited with the fellow building it but haven't been back to see how it turned out. It isn't too noticeable from the highway because it has a couple of A-frame extensions that really camoflage it's round "core".
