The curtain wall surface articulation reinforces the vertical movement of the design. The walls are convex and the central section stepped forward, giving the tower a rounded, beveled appearance. The vertical window mullions are shaped like airfoils, tracing sharp lines from base to crown. The tower is clad in lightly reflective vision glass and fritted spandrel glass that softens the tower’s surface. With specially formulated pearly silver paint on the aluminum components, the tower glows warmly against the peak and the city. The tower culminates in a spectacular sculptural crown. Its open design draws the sky itself into the tower top, partially dematerializing the building form as it reaches its highest point. When lit up at night, the tower top is visible from miles away, welcoming one to the harbour gateway. The project is LEED Gold^®.
