Definitely the most distinctive element in Herzog & De Meuron's winning design is its concrete structure. Appearing random, the concrete ribbons that start at the ground and curve over to the oculus are intersected by more ribbons that wrap the building around its perimeter. This system allows for resistance of forces in multiple directions, while also being the project's primary image generator. Together with the form, it helps to create something that appears like nothing before it in architecture.
