The Colonnade is an element which lines the oasis and creates a continuous shaded walkway at grade and a continuous terrace at first floor. The arrival sequence at grade proceeds from modest lobbies through grand interior atria which are lined by circulation and collaborative space. A dynamic roofscape which is simultaneously evocative of sand dunes, ship sails, and tensile tent structures is envisioned. In this option there are more discreet connections to below grade spaces that correspond to moments where there are stairs connecting the terrace levelto the oasis.
