Those kind of modern, round and organic-shaped building only work in Europe where there is a set, strong and historic infrastructure and architecture that shapes the built environment. Designing a building as abstract and jarring on the West Coast would just feel like someone is trying to mimic Disneyland. In many ways the lack of permanent infrastructure and the overly temporary feel of almost every erected structure and building makes the eye not take the extremeness of the building serious but rather brushes it aside considering it wasted playfulness.
In Seattle we have the EMP and the Downtown Library that are modern and abstract designed and the EMP feels lost under the Space Needle, build in an area without any focus or substance. The library is in downtown among somewhat older high rise buildings, right within a rigid street grid. Thus it feels a lot more placed.
