Now topped out at 33 storeys at the southeast corner of Church and McGill, construction is now in the late stages for Tridel's Alter. We last checked in on the construction of this architectsAlliance-designed Downtown Toronto condo tower in August of last year, when forming had reached the 26th floor, and cladding installation had begun to hint at the development's completed look. Since then, structural forming has wrapped up and plenty of progress has been made on the tower's exterior.

Alter is being clad in a mix of a window wall system with black frames, spandrel panels, and a zigzagging frame of white aluminum panels installed in three-storey intervals. On every third floor, the frame snakes back to the other side of the building via a line of white balcony guards.

A photo of the building, below, from the northeast, shows how the unconventional zigzag pattern sets the building apart from its neighbours, making it easy to spot on the local skyline.

Upon completion later this year, Alter will introduce 340 new condominium units to the city's Garden District, anchored to the Church and McGill intersection by 2,336 ft² of retail space. The podium levels will provide 34,300 ft² of office space as the new home of Family Service Toronto, returning to the property they vacated to allow its redevelopment.
