Proportions and to some extent symmetry play a role in the feeling of beauty. I theorize that as our ability to "engineer" things has increased, the various natural constraints of materials are falling away. Over thousands of years, those natural constraints developed into our sense of proper proportions, and a feeling that if certain things are not symmetrical then something is wrong with it. We don't have to do that anymore. We can get "more" out of our buildings, or conversely we can get the "same" but with less material or lower cost. The consequence is that such things do not really feel beautiful.
