Here’s what I wasn’t impressed with: how little there was to see inside this massive structure known as the Dongdaemun Design Plaza. Not sure the folks running this joint know how to present exhibitions or understand the art of curating. There were no permanent exhibits. This 3D building took 5 years and $450 million to build and there is nothing to see inside?!?!

But to be IN the architecture is the point. Thrilling. Like Eiffel Tower
Agree. You do feel like you may have vertigo once in the building. 3D aspect.
Seeing all that concrete reminded me of this recently-released statistic (from Vaclav Smil but widely publicized by Bill Gates, so it must be true):
China used more cement in the last three years than the U.S. used in the entire 20th century.
