The dome measures 212 meters in east–west direction, 144 meters in north–south direction, and is 46 meters high. The main entrance is at the north side. Guests arrive in the building after walking through a hallway that goes underneath the lake. The titanium shell is broken by a glass curtain in north–south direction that gradually widens from top to bottom.
