At first glance, this building, located in South Korea, may not look very big at all. Look again. Not only is this building structurally unique, it is also huge.
After taking a closer look at the photograph, you should spot a white van/truck, which is located on the left-hand side of the photo and it will give a much greater sense of the buildings actual size. Pretty cool! Thanks to San Antonio Ford for bringing this photo to our attention.
