Watercube, National Swimming Center is a unique waterpark in Beijing that was designed by PTW architect group. I think the outside of the building is very interesting and cool because the walls look like huge bubbles and change color at night. I think the color changing bubbles gives the building a fun appearance which attracts and amazes people nearby. When I saw this building for the first time, I could imagine it as a fun and popular place friends and families go to hang out at during a nice summer day or fun night cap. Even the structure outside the building brings people together as it has an open area with lights and water fountains in the ground kids can play in. I also find the bubble looking walls interesting because it easily allows natural sunlight into the building and brightens up the inside the waterpark. A positive aspect to this natural lighting, is that it allows people to enjoy the indoor waterpark and not have to worry about getting sunburn. Although this building seems very fun and exciting, I can also see the clumped bubble design to look very busy and distracting. Since there is a water park and recreational facility inside, I view that the bubbles may be too much for such a busy and active place.
