the complexity of the roof form is reflected in the interior spaces , where the folded-plate system allows a large column-free space. the folded of the folded-plate system change in response to the undulating surface of the building itself and this creates an interesting pattern that guides the eye. the use of such a structural system also means that the building is extended longitudinally in one direction , creating a series of spaces that are symmetrical but continuously changing. the variations themselves result in the experience of space closing in and then opening up on the observers as they make their way from land to sea or vice versa.
