The upper, private zone, has a more closed character and is clad with copper. This copper-clad "box" is carried by thin steel copper-clad columns with glass-panes and Western Red Cedar tiles in between. This provides the central zone with a more transparent appearance for the main living area. Below this, the concrete hull is the carrier for the arks upper zones. The horizontal jumps in the roof mark the horizontal division of the rooms and spaces. This horizontal spacing is also emphasized by the use of a split-level build-up.
