Designed by Wood Marsh, the building comprises two key elements a five-level podium and a 35-storey tower block. The organically formed podium, designed to represent the city grid and the river bank, has a sculptural, serrated skirt of tinted glass and anodised aluminium sheets. These oscillate vertically to create a continuum of rhythm.
"The curvilinear form of the podium also responds to the bend of the river's edge, and was designed to provide a fluid transition between the angular geometry of two towers Tower 5 and the proposed, neighbouring Tower 6," says Pie.
Tower 5's sharp-edged, diamond-shaped tower has an inner form of glass, subtly sculpted to reveal a bronze torso to the Flinders Street axis. The top of the tower is truncated away from the axis, culminating in a crown of bronze blades that conceal the roof plant room.
At ground level, the building's glazing is set back from the podium facade to create a protective walkway to the multi-use spaces, and to the building's entries. The riverside entrance is further highlighted by an undulating coloured-glass wall that provides a sense of fluidity, helping to visually connect the building to the waterfront. It also helps provide a human scale to the entrance.
"The glass wall is another highly sculptural element that complements the exterior architecture," says Pie. "Its sunset colouring, which was partly inspired by a painting in the lobby, adds a splash of brightness to the public spaces in front of the building. It also serves as a wind break."
