the design panel is requesting some changes to that concrete wall..
exerpt from the minutes
"A couple panel members questioned why the width of exposed concrete on West Pender was the same for both towers, and suggested the width of exposed concrete on the short east tower could be narrower. A couple of other Panel members suggested adding narrow slot windows to the stair wells of the exposed concrete core walls in order to create a playful element and to give a more interesting light at night as well as to add natural light during the day.
Some of the Panel liked the LED lighting designed for the south side of the towers as they felt it would give a night-time signature to the building, however others raised concerns about potential light pollution."
here's some additional renderings.
