Recently constructed in Seoul, Korea is a Commercial and Entertainment Center which you can tell by simply looking at it that it is green. Designed by MassStudies this entire building is covered in moss. Not only is the moss on the outside but parts of the inside as well. The stairwell leading down has its walls covered in moss giving this place a very unique feel to it. I wonder how hard it is to maintain it looking so nice though.
