As construction work closes in on grade at Mizrahi DevelopmentsThe One at Yonge and Bloor in Downtown Toronto, anticipation is building for the  Foster + Partners and Core Architects-designed project set to become Canada's tallest building. Though it will still be several months before the tower begins to make its impact felt above the intersection, we’re getting an exclusive advanced look at the exterior finishes that will define the supertall tower.

A cladding mock-up installed off-site provides a first taste of the tower’s cladding, a mixture of brushed aluminum and glazing which Sam Mizrahi describes as having bronze champagne coloured hues, not as easily seen in the shade as per the image below. The brushed aluminum panels will cover the tower’s hybrid structural exoskeleton’s exterior components, while curtainwall glazing will make up the primary building envelope.

The matte finish brushed aluminum panels will be an integral part of the exterior, surrounding the network of concrete-encased steel that will form structural "hangers" along the outside of the building. Like the curtainwall glazing currently being installed at CIBC SQUARE, these aluminum panels will feature built-in spotlights that will dramatically light the tower’s geometric exterior after dark.

The tower’s massing will be broken up by a series of four two-storey mechanical sections. These mechanical levels will be finished in grilles of cylindrical aluminum bars, filled with a dampening foam and backed by glazing.

The materials take on different tonal properties responding to varying lighting. A closer look with lower lighting better shows off the bronze hues of the mechanical cladding.

A rendering of how the 308-metre-tall building will look upon completion helps to put the mock-up photos in perspective.
