Early models of the interior (click for image) illustrate how the idea of the skin extends through the building, with horizontal tubes extruded from the rhomboid shapes acting as structural, spatial and display elements. In the first case, these elements brace the building from horizontal forces; in the second, they are occupiable containing dressing rooms and other functions; in the third, the exterior faces allow display opportunities. It remains to be seen to what extent these pieces were executed and how successful their presence becomes, though their potential is great because they alleviate the character of the interior as merely slabs and columns set within the exterior shell.
